Want to last longer in bed? The STU (Stamina Training Unit) was specifically designed to help men improve their sexual endurance. The Stamina Training Unit texture--made of large, pillow-like bumps--helps to prolong your sexual experience. Using the Stamina Training Unit can help with premature ejaculation and performance anxiety.
When you use the Stamina Training Unit by Fleshlight, not only will you be improving your sexual stamina and techniques, you will also experience intense orgasms that can only be achieved by using Fleshlight products.
The Stamina Training Unit Fleshlight has been developed for enhancing sexual prowess through training of the ability to control the speed of ejaculation. The Stamina Training Unit has a canal diameter of 0.45 to 0.6 inches (12-15 mm) and is thus relatively tight. The inner surface is covered by numerous large-sized bumps that protrude deep into the canal. The bumps are positioned very close to one another, forming a highly dense texture that runs throughout the entire canal.
The highly dense bump texture applies remarkably intense stimulation on the penis. The bumps work like many little fingertips that press, caress and massage the head, rim and shaft of the penis from all sides, creating an overwhelming stimulation sensation. At the same time, the penis is grabbed closely by the long-stemmed bumps and literally has to fight its way through the dense forest of bumps. This is all topped off with the accompaniment of a strong suction effect, which reinforces the fantastic stimulation.
This intense stimulation leads you, during continuous movement inside the canal, to a powerful orgasm within a few minutes. In order to delay the orgasm, you inevitably have to take a short break or to vary the speed of stroking. This is exactly the skill that you can improve by practicing with the Stamina Training Unit because the control over your own sexual arousal and personal stimulation threshold is the key for improving your sexual stamina. With regular use, you will quickly notice the results and you will learn how your body reacts and how much stimulation is bearable at which time. If you are able to masturbate with the Stamina Training Unit for a longer time and if you have, despite the intense stimulation, control over your personal timing of ejaculation, you won't have any problems with premature ejaculation during actual sex and you will able to satisfy pretty much every woman.
Full Unit Measures 10" (25cm) Long and 4"(10cm) in Diameter.
The cleaning of the densely positioned bumps is a bit time-consuming because lube and sperm residues can gather between them. In order to thoroughly clean the inner canal, you should turn the insert inside out during the clean up. The drying time is a bit longer than average, which you can shorten by wiping off the inner canal with paper towels.
This sleeve was also made in a limited edition vibro sleeve in ice with the lady/butt orifice, vibrating bullets were clear case and had LED's in them making the sleeve glow, limited to 500 of each orifice.

For reference I am 6.5” in length and 5.25” in girth,
This sleeve has a very specific purpose for someone who’s only goal is to reduce the chances of premature ejaculation when being with a physical partner. The sleeve is very intense as it’s designed to make you cum quick so it does the job however real sex is never as intense and the sleeve does get quite boring after a while, not much enjoyment, simply trying to resist the urge to release.
Rather than enjoying the process of battling PE this sleeve simply made me want to get a sleeve I’d probably enjoy more and not find as boring. This is a very practical sleeve but just not really enjoyable.
Clean up was more of a hassle due to all the small bumps so overall not worth the effort in my opinion.
In short this sleeve is super intense but very boring and anyone wanting it to increase their stamina is better off choosing a sleeve they’d find more fun as it would probably aid their goal anyway whilst being fun
The Stamina Training Unit was, for me, part of a larger purchase back in 2009 consisting of Wonder Wave, Super Ribbed, Vortex and STU.
The STU is marketed as a tool for frequent use resulting in lasting longer in bed with a real person. This is mainly because the texture is so decked out in small, stimulating bumps that the intensity of the sleeve will make you succumb to the inevitable orgasm far quicker than the real deal. In a way it almost feels like it was made to desensitize your member. But aside from that, how does the sleeve perform?
It is, as you guessed by now, intense by design. This texture will make you climax fast through consistent thrusting and is so intense that moving around post-orgasm can be somewhat uncomfortable (sensitive guys beware!). Due to the repeated, monotone texture, variety is barely present, but in turn makes it a good choice for guys with smaller members as there are no textures in the back you're missing out on.
If you're looking for realism, this is not it. Although, as described above, it was never meant to be realistic. The sleeve is pretty tight which adds to the intensity but makes the bumps feel less pronounced as they're all squished up against you. Due to the tightness you can at least get a nice suction effect going. Clean up and drying time is not that great, as a lot of moisture gets trapped between the bumps. Helping things along with a fan or a folded piece of paper towel is definitely recommended.
As with the other classic sleeves, this one is overshadowed by newer, more interesting alternatives on the market. If you're looking for building stamina, there are Sleeves which are either tighter or more intense than the STU in the FL Girls lineup alone, all of which are certain to be more interesting in the long run. This is still an okay sleeve for a quick session with good amounts of tightness and suction, but I cannot recommend it.
Just an average guy. 5 inches on a good day with a girth of 5inches. I prefer realistic feels or sleeves that gives a mild experience.
This was my first ever sleeve and I enjoyed using it for the time I had it. It is a tight sleeve with the sole purpose of climaxing quickly to train yourself. The sleeve is easy to clean and did not make much noise when using it. It does not need much lube to use and its pretty much a straight forward sleeve. I did not find myself feeling much of the textures inside for someone of average size but I see others have so your mile may vary. Overall its a decent sleeve for its job
I ended up retiring this sleeve and wanted something I can enjoy more. If you want to train yourself or just get their quickly then this is the sleeve for you.
I am a long time fan of this texture. I love it. Sadly it's not as it is advertised unless you use it in a strict regiment to where you could feasibly improve with just your hands.
The STU is a great middle of the road texture. With several other sleeves, you will find yourself having different experiences with a generous portion of the sleeves available. With the STU you can find just the right way to get yourself going and control it to an edge thinner than a razer.
It is an intense sleeve for sure, but once you get use to it, it will be an enjoyable experience that can be driven at a pace that can give you multiple different endings.
There are some sleeves that give too little and others that give too much. The STU is just right.
I really like the basic lady entrance, but Pure has to be one of the worst. I’ve had 3 of these now and pure took so much out of the experience that I bought another lady.
It feels slightly tighter than average because of the amount of nodes in the texture. It doesn’t squeeze as much as it hugs. I find it very comfortable.
There are very few textures that create their own suction effect without the help of a case. This one clings on just a bit
This is built to be way more intense, but I feel like it starts to get there and falls flat with a lack of variation.
There is little but the nodes are not all in a row. They alternate in a comfortable way.
You can feel very node in the texture.
Any kind you want. Quick and exciting, slow and soothing, and anywhere in between.
It kinda squelches a bit, but no fleshlight is crazy loud.
Less than you would think, and once you get going you rarely need more.
Again better than expected. The nodes aren’t crazy deep so it is pretty easy to clean.
Not great and not bad. Dry as normal.
I can’t express how many times I’ve use this and wanted more. It is one of the best for a middle of the road marathon to have fun for hours in my
If you are looking for top speed and intensity, this isn’t it, but if you want a soft cuddle buddy for your “buddy” I would recommend this as one of my top 5 because of the satisfying nature and it’s ability to not overstimulate.
For reference I am uncut 5.8 inches in length and 5.0 inches in girth. I normally use my fleshlights cold with fleshlube.
The STU was my second ever sleeve, my first being the original and let me tell you, the STU was a massive upgrade. I never went back to the original after that. The STU is quite an intense sleeve and as a result it takes a lot of practice to alter your stroke speed to not go over the edge, hence all the marketing buzz around this product. The fact that the texture is not varied gives you more control in order to delay your orgasm as there isn't any sudden changes in the texture that may blow your load.
As I mentioned, the sleeve is up there in intensity. Really for me it's too intense as I find I'm only stroking about half the time and taking rests the other half of the time. I have Riley Steele's Nipple Alley and it is very similar to the STU as you can see from the texture images with the difference being is not as tight and as a result, not as intense as the STU and for me this makes it better in my opinion as you have less "down time" trying to recover from the intensity and I can continuously stroke unlike the STU while still edging and training yourself not to finish so quick. A bonus to this, Riley's sleeve has a better appealing orifice so If you're still considering the STU, I would also consider Nipple Alley for the points that I have made here.
I have used the STU as my exclusive masturbator for about 5 years (2012-2017). Around 2017, I started to explore the FLG line and since then, I now own 9 different fleshlight girls and I rate each one above the STU. Since the STU came out, fleshlights have come a long way and their newer textures are far more exotic and exciting so I would have to recommend them over the STU but saying that, the STU is still pretty OK.
I believe Nipple Alley is a better "Stamina Training Unit" for the reasons highlighted in my review however the STU is still a decent sleeve. I just think we're spoiled with better options these days with the newer fleshlight girl textures.
I'm French i'm an 5.6 in long and 5.0 inch girth, I'm not circumcised and I'm pretty sensitive to the dick I have a nice collection of FL, I don't use fan for drying just hanging on a towel holder I have as accessories FL: "sleeve warmer, shower mount, launch" I prefer the FLG (lady and butt) Before review I will have used min 5 times I will have warmed the Fleshlight My masturbation routine with FL are with 2 FL I start with a pussy orifice not too intense and then I take a tighter sleeve (pussy or ass) and I like to finish with the first softer sleeve before enjoying generally I use 2 shower mount, which I fix side by side to be able to alternate my penetrations I would be very happy to chat privately with you feel free to contact me and put me in friends thanks for reading my reviews ,excuse me in advance for my bad English
this is my first sleeve bought from my collection of FL
its appearance is classic, its uniform texture with small balls is of a mean inteensity to me, penetration is good and we tighten the softness, not bessoin to use a lot of lubricant
I do not rank in the top 10 of my FL but there is still a value on to start
I often start my FL seance with STU and then pass with a FLG
very good start sleeve, by its softness and ease of cleaning
I've been using this sleeve for about 5 months now. I bought it as my first Fleshlight in May as a birthday gift to myself. It has increased my stamina a bit but I'm not sure if it is due to the texture or if it is because I use it daily. It feels great compared to a hand, it is smooth and not too stimulating for a first time user. My orgasms have been much greater with this sleeve than without. It is very easy to use and clean and doesn't take too long to dry.
Overall good product, would recommend for a first FL. Smooth, repetitive texture doesn't overwhelm a first time user while still giving a great feeling and a greater orgasm than any hand could give.
This is the third Fleshlight I have tried and I can say there is a good reason for this being the top selling product. My first time with this sleeve was one of the longest masturbation sessions I have ever done as I lasted well over twenty minutes. By comparison I lasted less than three minutes with the other sleeves I tried and that is about what I can do with my hands under normal circumstances. I warmed just the sleeve up with the warming accessory and then applied the 10 mL trial packet of lube to the orifice. It didn't take me long before I added a good squirt of Astroglide liquid because the noise and suction were annoying with the cap fully closed. Towards the end of my session the texture was getting quite rough and I started seeing white flakes that I assume were the lube drying though misting water didn't seem to help. The orifice is certainly tight enough you should be fully erect before inserting it into the sleeve, but by no means uncomfortable. I would say the mouth and lady orifices are about equal in terms of tightness.
While I felt comfortable putting my previous sleeves up after an overnight dry, this sleeve is still noticeably damp even after drying overnight.
My second use was using hte Sophie Dee VStroker video with the VStroker attachment. This is a sleeve you really should use at your own pace with plenty of pauses as necessary. I could not last trying to keep up with the video.
My third use was nothing special but I lasted 20 minutes and found the suction with the cap fully closed to make things impenetrably tight.
Best texture I've tried so far! Eats lube, but easier to edge with. Expect long drying times.
I'm 5.6 inches long and circumcised. I have 28 fleshlights/fleshjacks total. I dry by placing by fleshlights in front of a fan overnight and they are always dry come morning, so I do not put drying time on my ratings. As for realism, being a virgin, I am unqualified to rate it.
This sleeve is rather boring. This was probably around my third or fourth sleeve. I used it for I while and eventually shelved it. I pulled it out again for this review and am still just as underwhelmed. The bumps are stimulating, yes, but there are much better options. Trigger and Nipple Alley off the top of my head have similar designs. Give them a peek first before deciding on this one.
I quickly grew bored with it. There are much more exciting sleeves out there.
I am cut with 7.5 in length and about 6 in girth. I typically test my fleshlights cold at first then warm them after the break in period has ended.
Everyone runs to this sleeve because they feel it will make them last longer in bed. Well this in theory is true but its also true with every fleshlight.
I have this fl and I use it mainly for its intention of edging I also use more intense sleeves for the same thing. Where this has an advantage is this is the same texture all the way through. This is nice because the whole thing feels the same and makes it easy to know what coming. It is a.nice sleeve amd is great for a first purchase if you feel the flg line is to overwhelming to pick from.
Although this is a pretty stellar sleeve the alien is basically the same sleeve with the lotus node and twisted front. The stuff is nice but is second to the alien
I have this STU for about 5 months now. It is enjoyable so much so that I may even say fantastic and has helped my stamina greatly. I can go for longer periods in the bedroom and my partner admits our intimate sessions is greatly improved. I used to be sensitive before and would climax way too soon, just when the fun just began. Get way to excited and couldn't stop ejaculating. After using this fleshlights for a few months now I have much more confidence and control and I can go for longer lasting times. I find it easier to please my woman now. She climaxes and I can go on and on. My penis has also become stronger and maybe a little bigger with all the practising. This training is far much better and fun than any other sport or activity. This is a great toy. When warmed and lubed properly it feels just like the real thing except tighter like a virgin.
This is a great toy and will recommend it to any guy. Expensive but feels like the real thing. Thanks guys.
The main reason I wanted to try the STU was because I had developed what is known as Death Grip Syndrome. Basically, this means that masturbating by hand over the years had caused me to become overly desensitized to stimulation. For this reason, I thought the STU would be the perfect sleeve for my needs. What it lacks in variation, it more than makes up for in intensity! The nubs found through the entirety of the sleeve are pure bliss, and the first couple times I used it, I'm embarrassed to say that I didn't last long. After using it for some time, I've been able to last longer, but the orgasms are just as strong as they were the first time. Whether you want to last longer, or are looking for an alternative to your hand, the Fleshlight STU stands out from many other traditional toys.
I like the tightness and intensity of the STU. I never have a problem getting pushed over the edge with this thing, which typically results in shorter sessions than usual. When I don't have as much time as I normally would to fuck my fleshies, I use the stamina training unit more often than not.
i love the lady vagina appearance on the outside. when you penetrate you feel the tightness around your member. the undulating bumps are so tight but good. you will cum pretty quickly and it trains you to edge and hold on. you need quite a lot of lube because the lube gets stuck in the cracks. overall is not too difficult to clean.
great fleshlight for testing your stamina and training yourself to last longer in bed
Not sure what the fuss is about this. Firstly, the sleeve material has this weird scent and is a lot firmer than the usually sleeve. If you like to grip your penis really tight when masturbating, you'll probably like this. Personally I find the material too firm. There's not much in the sleeve texture either. I can feel the large nubs but they don't really do much for me, nowhere near the Brent Corrigan Bliss texture. I wish I hadn't spent money on this and gotten another Fleshjack Boy instead.
Don't get the fuss. Material has a weird scent and is really, really firm. A bit too firm and tight so not as enjoyable as Fleshjack Boys.
Welcome to another review by yours truly, revtwentyseven! A few points of info when reading my reviews: I am circumcised, use Gun Oil H20 lube, and generally FLy several times with each sleeve, including once immediately prior to the review. Most of my reviews reference how that review FLight was accomplished. Now on to the review for the:
I got the STU as part of the Library Girl Study Pack (along with the Kendra Sunderland Angel FL), marking the second time I got an STU (my first FL all the way back in 2010 was a STU, but poor care and paranoia about storage forced me to throw it away after just a few months back then). Combined from 2010 and now, I have well over twenty FLights that I can easily recall, including quite a few since I reacquired it again.
Aesthetics: As a fellow FA member commented, aesthetics should be considered with the overall review. I agree. The generic vulva is anatomically correct... too correct. Although there's no denying it looks pleasing... it also looks generic.
Lube: In the case of this review, I used ID Glide water based lubricant. It is wise to keep the lube on hand, because if you go for any great length of time, you're gonna need more. If you are in doubt mid FLight, use more.
Noise: The noise made by FL's don't bother me much, and unless someone is actually watching you going at it, it's probably not that big of an issue.
Penetration: The STU is known for it's one unified texture: a tunnel of pillow like bumps from start to finish. Although they do feel pleasurable to thrust in and out of, these bumps are going to increase in stimulation rather quickly... leading to...
Intensity: The STU lives up to it's billing in wanting to make you last longer... in that the intensity ramps up incrementally yet quickly, leaving you with two choices. One is to to change your thrusting or stroking technique, the other is to head for the exit ramp of the FLight and orgasm.
Orgasm: With a FL, there are three orgasms that tend to come about (pun intended). One is a gentle buildup that leads to a nice orgasm. Another is one that causes you to cum without warning. The last is a "when you blow, you know." The STU is exclusively in the final category, and the intensity of your orgasm is generally dependent on how long you were able to hold out. There's nothing subtle with the STU, from it's bright gold case to the sleeve design, to the finish you will have with this thing.
Cleanup: The STU can be a bit tricky to clean up. Although you may not want to, you need to run warm/somewhat hot water down the sleeve canal as soon as possible to remove deposits. A paper towel can help mop up the moisture, but be careful, or it will eat a part of your towel.
If you are looking for a FL to help improve your sexual stamina, the STU has been the go to choice, and one should not discredit the original simply because there are new options available with stamina training like features. Otherwise, it's not a must buy FL, though it makes a nice add on for a deal package.
I always saw people saying good things and hyping up the STU and while personally it doesn't live up to the hype it's still a pretty good sleeve. Like the Torrid sleeve this was one I always looked at a lot but would pass up for more interesting looking textures and I finally caved and picked it up as it's kind of hard to pass up all those freebies (also the "wonder what mystery sleeve I got" game). I wanted another "uniform" texture sleeve like the Vortex because while all the crazy textures and sensations being added to sleeves it's nice to have 1-2 that are consistent all the way through, especially because those sleeves, at least to me, are better for endurance training than the very varied texture sleeves. Cleaning and drying is a little intensive due to all the little gaps between the bumps that hold lube and semen while cleaning and then those gaps hold the water which makes dry time go up quite a bit if you don't place it in front of like a small fan
Not the best but definitely not a bad sleeve, I'd give it a solid B (85/100)
–Reviews For Girthy (or more-sensitive) Guys–
TL;DR sleeve summary: 5/10, a very average, basic texture. Medium-high intensity, with no variety or unique sensations. For the most part, the Alien sleeve is just a more-interesting, varied, and enjoyable STU.
Sleeves work completely differently depending on girth, so these reviews are here to help average-length girthy guys find the textures that fit best. Those with sensitive members may also find this info helpful, as the effect is similar even if not 100% comparable. Whether due to girth or sensitivity, you don’t want textures that scrape badly.
Info for reference: just under 6” length, 7” shaft girth with a 5.5” head that’s fairly sensitive; all sessions done with sleeve flaps cut off (for looseness) + Fleshlight warmed & locked down horizontally to thrust into (for better feeling sensations). If you’re girthy, but not 7” girthy, awesome – way more sleeves will work for you! Average these reviews with others, according to where on the girth spectrum you fall.
NOTE: if a sleeve works poorly for your girth due to the case allowing no more room to stretch, cutting a layer off the sleeve’s ring (that sits behind the case’s ring) can work wonders to reduce pressure and let you feel everything better. Just be careful of the sleeve falling out if used vertically, and always test out small adjustments before modding a sleeve any amount.
Needs girth mod: No. It felt a touch looser after removing the ring, but wasn’t exactly a pronounced change.
Smoothness: 6/10. Doesn’t scrape badly, but can still leave you a little red from roughness after a while if not careful, especially if thrusting quickly.
Intensity: 6/10. Fairly average, and acceptable to edge in. Neither “can’t control myself” nor “I can hold out forever.”
Sensation: 6/10. The bumps stretch around you to the point that you don’t feel anything distinctive. It’s just vaguely soft, but not in a slick Lotus way... there’s still resistance.
Intensity During Orgasm: 5/10. It’s ok to stroke through if you’re sensitive during orgasm, but not a great sleeve for it.
Overall Experience: 5/10. Still pleasurable, but in no way exceptional. I’d greatly recommend the Alien over it, as it contains the STU texture but with other interesting elements as well.
Getting out of a long relationship, I quickly realized that I wanted some additional assistance on the orgasm front. After trying out a Tenga Flip-Hole and having it break on me after 6 months of heavy use, I decided it was time to go back to the Cadillac of fake vaginas and bought my first Fleshlight since college. After some shopping around, I settled on the STU, mostly because I found a good deal on it, but also because so many of the ads and reviews raved about how intense and tight it is. Well, I've been banging my STU for a few months now, and I feel like I have enough experience to write a fair review of it.
First off, those guys who are out there saying this is the most intense thing ever must have some hair triggers, because I found the STU to be fairly mellow experience. That's not a bad thing; in fact, I think this is a great sleeve for edging, and I finally had a breakthrough in achieving multiple orgasms with it after months of trying with the Flip Hole, so I think it's a great sleeve overall. But if you're looking for something that will make you blow your load after a few thrusts, this probably isn't what you want. At the risk of humble-bragging; the ads say "if you can last 10 minutes with the STU, you can last 20 minutes in bed with anyone." Well, my sessions tend to average about 30 minutes, so I guess that makes me a 60-minute man!
Joking aside, the sleeve is tight and feels velvety, allowing for some soothing, prolonged sessions that just feel amazing. But I think I will buy something more intense to alternate it with; variety is the spice of life, after all!
This is nowhere near as intense as you've probably heard, but it still feels great. I'd say it makes a good Fleshlight for beginners, but if you're already more advanced, you'd be better off looking elsewhere, unless you need a really solid edging sleeve.
I got the STU as a free mystery sleeve during the last Valentines Day sale. Interestingly enough, it came with a butt orifice, which I have never seen offered before, and can't find anywhere on the store now. ILF advertises that the STU is supposed to help increase sexual stamina because of how intense it is. After using it, I can certainly agree that it is intense, but in a more simple way than some sleeves. The best intense sleeves create intensity by having varied textures and tightness, whereas the STU is uniform throughout, which is good for shorter guys since they won't be missing anything a more well endowed man would feel, and gets it's intensity through the rough feeling texture. As for the whole "stamina training" bit, it's just an advertising gimmick, any intense sleeve could help you build stamina, so don't buy this one on that pretense alone.
If you want intensity, don't just go for this one by default because of the advertising. If you like rough sensations and uniform sleeves, this one is perfect for you.
About Me: I am 25 and have an athletic build and a 7.5” x 5.5” circumcised dick. I have a sensitive cock and have had multiple sexual partners. I am actually engaged so I regularly have sex. I have a short refractory period, so I can usually cum once quickly and then a second time after a decent time without even exiting my fiancée. This is from my very first FleshLight haul ever, so I am a beginner with FleshLights, but I have used a stamina training sleeve in the past.
Penetration/Orifice: I am using the free FleshLube included in the purchase. I start by teasing the labia and orifice with my cock. The lips actually look pretty inviting I think. They feel decently close to a real labia I think. Very fun to tease your whole cock with. Tight entrance.
The Textures: The whole thing feels like a massage for your cock, all over.
Intense! I could only edge for a little bit with this one, I do recommend this!
My first and one of my favorites. This is the only fleshlight I own with a consistent texture throughout the sleeve, which is something I can appreciate. Other sleeves look more visually appealing with all the bumps and teeth and openings, but this sleeve proves that less is more. It is very stimulating, more realistic than most other sleeves I have tried, and I can play around with how much I am inserted in it because the pattern is the same at the beginning and end.
Super stimulating, consistent texture, and more realistic than many other sleeves.
This was my first Fleshlight. I has been great, but I rarely use it anymore. I have since purchased the Go Torque and the Flight Pilot. The Pilot is my go-to for travel and the Torque is my wife's favorite for partner play. The STU is a great "general use" (rather than specialized items like the Torque and Pilot). If you buy only one, the STU would not be a bad purchase.
My only complaint is the size. I don't need something 9.75" long. A shorter Fleshlight is less tiring to use.
Great overall Fleshlight. Recommend if this is your first purchase.
STU was my most used sleeve. It's stimulating but not too intense, which really makes it a good option to train stamina. There is no variation in the texture across the sleeve so guys with all sizes should enjoy it equally. Although it might look boring at first, but the texture transform well as your cock gets bigger and bigger due to stimulation. It feels much more intense when close to ejaculating, when the cock head is swollen and sensitive. I find the soft bumps ideal for building up and having a satisfying orgasm. The texture is also relatively easy to clean and dry. Always a favorite.
STU remains one of the classics that goes well on its own or with others.
THIS IS THE PERFECT FLESHLIGHT FOR YOU TO GET YOUR STAMINA UP!!!! The entrance is mega tight and slides you into the speed bumps that will, one first use, have you cumming like crazy. After a while, if you use it like intended, it will help you build stamina by resisting the temptation of pleasure. The bumps caress and massage your cock so gently that you'll never feel sore no matter how many time you use it. It's perfect as a first, only, and last fleshlight that will satisfy you. Plus the gold case make your feel like a champ.
If you want to last longer and want some serious orgasms, this fleshlight is for you. It also helps to increase stamina. But your first few times will decrease because it's so intense, you're gonna have to get used to this sleeve.
The STU is heralded on the site as a good fleshlight but I think it has quite a few shortcomings. no pun intended. I don't really see how its supposed to train your stamina in any way because its just plain and doesn't feel very good. They could've called this texture bumpy or something normal because that's all it is. bumps. I would use my money somewhere else if I had wanted to buy a new one.
I would not consider the STU, a good stamina training unit or a good toy. I bought one because the reviews were good and it was my first fleshlight so not a lot of them were on the market. Nowadays with the wide selection there are better choices out there.
The STU was my first Fleshlight and I definitely recommend everyone try it. It is a tight and intense sleeve, marketed as a sleeve that will help you last longer while having sex which I agree with. The pillows are intense, yet feel great and smaller guys don't have to worry about not being able to feel chambers at the end of the Fleshlight because it is all lined with these pillows. Ejaculating in the STU for the first time can be so intense that it's borderline painful to the flaccid head, so I would recommend breaking in the STU before ejaculating inside. I don't have a problem with DGS but I would imagine the STU would be a great Fleshlight to deal with DGS once broken in. Cleanup is easy, just rinse with cold water, alcohol bath occasionally, and leave out to dry or you can blow dry it with a hair dryer on no heat.
Recommended if you want to last longer and enjoy intense sleeves.
Okay the first thing people ask is does this work, Does it make you last longer? The answer is... YES! I don't know how many times I've worn out a woman without finishing myself. And, it wasn't always that way. I was a 5-20 minute guy before I got one of these. And, better yet is being able to power thru an have multiples without needing a break. Just use this, time your time, do the stop/start method over and over. You'll find your groove. And, when you uncork... slow down and keep going slowly. Before you know it, you'll last all night and not need a time out when you climate. Next is how do it feel. Really it feels great. Better then a Lotus to me. It feels pretty real. and the O's you'll get out of it are worth ever dime you spend!
I'm not being paid to say it but this is a great sleeve. Everyone should get one! If you are looking for your first FL. It's worth it to start with this thing. It will not be a waste of cash!
This is a great sleeve to be introduced to the fleshlight experience with, in fact it was the first textured sleeve I owned. I used it so much, and soaked it in my tap water so many times it became badly discolored and got a lot of those sticky grey rubber-like boogers all over it. Needless to say, I now soak my sleeves in bottled water to prevent the discoloration of any other sleeves and have replaced the stamina training unit (STU) with an alien. Sorry for the tangent- moving on, the STU texture is indeed a great endurance builder. If you can last with this sleeve, you must have some great physical and/or mental control. It feels so amazing, I really couldn't imagine anyone not liking it. If you could only own one fleshlight, this would probably be the best choice.
A great place to start, you will be hard pressed to find a texture that is better than this one at being good in so many ways. Great for endurance building, great for quick pleasure, gentle on your member, holds lube well, cleans easy, have you been convinced yet?
A little about my background at the start: I'm an average build circumcised guy and I'm really into strong sensations. Because of a very extensive style of circumcision it can be hard to reach orgasm multible times in a row. I'm sexually quite active with a pretty adventurous woman at my side, that luckily finds Fleshlights and me using them pretty hot. ;)
That one really is a hard review. I got this thing as is was marketed as the best thing since sliced bread. I expected very intense stimulation, just to find out it's a total fail on me. Similar to the original sleeve. While I expected the Original sleeve to be a fail, I was totally disappointed about that one. The stimulation on my circumcised penis is so very suble, that it is even hard to reach climax with it. I totally blame that on the circumcision, and I'm very sure, the pressure sensitive foreskin and frenulum area are needed for savouring that sleeve. That was actually the first and only time I ever wished my foreskin back! ;)
It feels pretty tight and as these knobs are already pressed flat against the penis, it feels VERY smooth and hardly structured to me. The extremely pressure sensitive foreskin is MAYBE able to detect the pressure differences and create pleasurable sensations by it. But as far as I'm concerned, this one was the most disappointing FleshLight fail to this date!
I don't rate the loudness as all sleeves are very quiet to my ears. The difference is irrelevant to me. That sleeve is easy to clean but dries only average due to the little air that can go through the tight canal. I have stored that sleeve in the cellar for whatever it might be useful again, but I don't plan on using it again!
For cleaning I use mild hand washing soap ("soap free soap"), which does not hurt the sleeves noticably, even the frequently used ones! I also use talkum and NOT corn starch. Moist corn starch is a perfect nutrient for molds and bacteria of any kind.
If you are circumcised, save your money! That thing is not for you!
Otherwise decide for yourself if you can trust the hype! Usually it is at least partially true...
This review is made purely out of my personal experience/opinion and judged after atleast 10 sessions to break the sleeve in completely. Typically used in shower with the shower mount after having heated up the sleeve and the lube.
Fleshlight's Stamina Training Unit is an average product compared the rest of the Fleshlight range in my opinion because all of the sleeves available will still apply somewhat of a 'stamina training ability' and the sleeve won't make anyone last longer than what they would if they were using any other sleeve for the same purpose of trying to last longer. Also they sort of try to rope you into buying it because of it's fancy gold case only availble with the STU. However being fair on the actual texture of the sleeve that comes with the product, it is a very soft and delicate texture despite how detailed the continuously bumpy texture is and has a tendency to become quite stimulating towards climax. But the detailed bumpy interior makes drying the sleeve take quite bit more time than expected.
Overall the STU's texture is good as it seems to have the ability to become increasingly stimulating towards climax, otherwise the long dry time is the textures let down.
This was my first fleshlight. I didn't take proper care of it, so it wound up in the grave yard after about 2 year of moderate use. This texture was INTENSE. I never lasted more than 2 minutes with this.The nubs are so, so soft, and the just rub the head of your dick, both going in and coming out. It's a sensation overload. It felt amazing and too much at the same time. If you're looking to up your stamina, this will help. If you have zero stamina, try building some with something else first and then work your way up to this.
Crazy intensity, will definitely help build stamina, especially if you have a FL or two already. May be too strong if you don't have any stamina.
My very first texture and for a first time it was good. The texture as time grew on became quite loose and I needed more to get going. I decided to opt for a texture that was a little more intense. As it was my first texture it was much bigger upgrade to doing it with my hand but after trying out more complex textures this texture pales in comparison.
Would I suggest this as a beginner texture, maybe, but there are better first textures out there.
The STU was my very first Flashlight (purchased back when Mocha was still an STU color choice :O ). After throwing it out, due to degradation caused by overuse, I have since bought another STU (this time pink color with the gold case) and have a combined total of approximately 150 flights in the STU, so I feel well qualified to review it.
It's definitely a good sleeve, though I rarely fly in it any more due to my preference for the Fleshlight girl sleeve material and realism. It's especially important that you heat it up for some time (I prefer about 20-30 minutes in very hot tap water, swapping water half way through the twenty minutes) because I feel the intensity of the texture is even more stimulating when hot, rather than just warm. The STU is a relatively tight sleeve, and it's well suited for fantasies related to relatively tight girls.
As with many fleshlights, I've found that if you can get past the first five minutes of penetration (taking breaks from the sleeve when necessary) it quickly becomes possible to last for ten, twenty, or even thirty minutes in this sleeve. If you pound away at it continuously, the STU will make you blow your load faster than you might like. For me, I think this sleeve is far too intense to continue pumping into during orgasm. I recommend that, when orgasm is imminent, you move the sleeve so that only about 1-2 inches of your member is inside, then as you start to cum rapidly move the sleeve downwards and push as deep inside as you can. In this way, you'll touch a part of the sleeve you might not have reached before (penis is slightly larger during orgasm) and cum even harder.
I'm somewhat skeptical of the 3/4/5/6/7 stroke shallow 1 stroke deep regimen recommended in the stamina training guide which comes with the STU. I think, as described above, it's most important to spend a few minutes getting comfortable with the sleeve, then start continuously pounding into it.
Great first sleeve. Recommend that it be heavily considered for inclusion in any first Fleshlight orders.
Before I say anything else, let me just clarify one thing: relative to other fleshlight textures, the Stamina Training Unit is not special. It should not be placed in a category of its own. It does not have magical stamina boosting properties that will make you last longer than if you were to practice with any other texture of similar intensity. That isn't to say that the STU is bad, or even that it isn't worth getting. The STU was the first fleshlight I purchased, and I do not regret that purchase. There are other textures out there that I like more, but I still use and enjoy the STU regularly. If you've ever used a fleshlight before, you can probably make a relatively accurate guess at how the STU feels. It isn't the most intense sleeve available, but it's at a moderately-high intensity level that I enjoy. The bumps just feel nice when sliding up and down your shaft, whether you're going slow or fast, hard or gentle. The lack of variation may be a negative for some people, but I think the STU comes together pretty well in general. I might not recommend the STU as a first purchase (I would probably suggest a mini lotus or flight pilot first), but it's definitely a solid pick for someone who plans to own 3 or more fleshlights.
It's not my #1, but the Stamina Training Unit is an all around good texture and a solid buy for someone who plans to own several sleeves.
First Fleshlight I have bought, have to admit it was a lot more pleasurable than I expected it could be. When I first got it I struggled to last for any time at all (and I can go for a good half hour with my, wonderful, girlfriend) but now can go for a good 10-20min with it (they weren't kidding when they called it the Stamina Training Unit, at least not by my experience so far). The first time I used it I wasn't quite sure how to go about it (whether to warm it, leave bottom cap open etc) but within a couple of uses I found my favourite way to prepare it. My favourite part of the sensation is just as you first go past the orifice and into the speed bumps, that feeling as you first go from orifice to bumps makes my legs go to jelly. Cleaning it is a bit annoying but not real issue, max power with the warm tap through it to blast out any ... 'juices'... then shake off as much water as possible before leaving it somewhere with very good airflow. I recommend dusting down with a little bit of cornflour/cornstarch if the stickiness bothers you (have to admit I find it a bit weird but nothing major).
Overall I would definitely recommend an STU to anyone considering trying out Fleshlights. I think it was perfect as a starter and have heard many others agreeing. Amazing pleasure, intensity, tightness and great orgasms too. Could be a bit tighter in my opinion but definitely very content with it as is.
One of the most intense sleeves out there. The soft, dense bumps feel really good when penetrating it and pumping through for the first minutes. I could easily finish with it but if I don't, it numbs me and becomes dull after a while. After some edging I can last for ages with this, and it actually becomes hard to reach an orgasm. I guess it's the combination of intensity and lack of variation that makes this numbing.
There are better textures available. For stamina building I recommend intense textures with variation, and for pleasurable long FLights something less intense.
The stu was the second FL I bought. And while I enjoy the stu I have to say I like the swallow more. This sleeve is intense but there is not enough variation. I honestly bought it because I found it on sale. It is a good texture I just wish they would have varied the texture up a bit. Also it could be a bit tighter.
In conclusion this texture is pretty good but I would have defiantly bought something else like the destroya or the lotus after reading reviews.
Longwinded Backstory: Back in early 2007 I was hornily perusing the internet for my very first sex toy. I had been experimenting with homemade contraptions that were pretty mediocre, sometimes borderline harmful and were hardly any better than my lotioned-up hand. I came across fleshlight's website and their forum. Some of the reviews in their testimonials section had me incredibly hard from the way they described their experiences with these things. I went back and forth on whether to take a chance on one until I learned of a special offer on the then new pink colored stamina training unit. Well that did it for me and soon a pink lady stamina training unit was on its way to me with a bottle of id glide.
First Impressions: When it arrived I was giddy (and horny). At first I thought I might've had a defective sleeve given the round protrusion near the lip of the sleeve where it inserts into the case however a quick check with forum members cleared that up. Holding the sleeve in my hands I was truly impressed by how soft and skin-like it felt. I immediately went to the bathroom to wash off the cornstarch and start soaking it in warm water (something I highly recommend every first time fleshlight user do as it greatly enhances the experience). I only made it about 15-20min (in retrospect it should've been more like 30min) before I eagerly snatched it up and wrangled the wet sleeve into its case. I had already been half-mast since I got the package home but applying lube to it really had me standing tall. Sliding my fingers across those lips and plunging them into its warm, soft, bumpy depths felt great I couldn't imagine how my dick would feel. Slicking up my shaft with some porn playing I started slipping inside. Sheer joy, no hand could match the feeling of those wonderful warm soft bumps engulfing my dick, tracing pleasure as they slide along down, nuzzling it in just the right way. I began slowly stroking up and down, up and down; my dick was in overdrive from the sensation. Unable to withstand the pleasurable onslaught I gladly surrendered my cum into its welcoming depths. Breathing a contented sigh of relief I looked at my screen to realize I hadn't even made it a minute before cumming, it was that good. Not that I minded much because it felt incredible. Admittedly my anticipation likely had some to do with it too.
Those bumps let you know when you're nearing climax as they really step it up in stimulation. Over the next couple months I significantly increased my session times while exploring new ways to enjoy it. ILF then released a new case design (the one we're familiar with today) and to promote it they offered a special where if you buy any two sleeves you'll get the new case and a pink lady speed bump for free. I couldn't resist, by this point the STU had worked its magic and I was hooked, eager to explore new sensations. This was the start of my collection.
Cleaning: Pretty easy, no real trouble with this sleeve.
Drying: Also quick and easy with my homemade hanger.
Speed Bump: Many people who don't own both the STU and speed bump often assume that these textures feel similar since they both are comprised of bumps. This is absolutely not true. Both textures provide their own distinct sensations that are very easy to tell apart. Speed bump is rougher (in a good way) and I am more likely to use it for a hard and fast session whereas the STU provides a somewhat sweeter gentler session (very pleasurable).
Summary: The STU is a great texture that I commonly recommend to people buying their first fleshlight given its cheaper price compared to fleshlight girls and you must buy it with a case. So why not buy one then get more textures in just sleeve form and save a few bucks not buying cases that you don't necessarily need. While it can sometimes feel a little mild (especially after having cum recently) the STU still remains among my favorite textures after all this time.
This happened to be my first fleshlight, I had actually set up a P.O. box and ordered it in order to hide the package from my parents when I still lived with them. I was even able to order it in a black case instead of the golden STUs generally order in.
Mine happened to arrive in the Vagina orifice, as I felt the pure orifice wouldn't do it justice.
One thing to note about seeing the fleshlight for the first time:
The case does not look like a flashlight at all, and is definitely not going to fool anybody.
You're much better off finding a good place to hide it.
But thankfully, I was able to keep it safe and secure for years.
And it did happen to last a good four years before I unfortunately forgot to wash the device for a good week or two, and had then decided that it was time to dispose of it. Also, do not use it with hand or bar soap, as the texture started to wear out when doing so. Just rinse it well, and clean it after every use.
Comparing it to the only other fleshlight I've had, this one takes the cake.
It's really easy to get off when using this, and the material is definitely convincing.
One thing you find out relatively quick: You must use lube in order to use it. Wish someone had told me beforehand, as the small shot it came with was only enough for one use.
For anyone more familiar with fleshlights: It's definitely the most intense sleeve I've used yet.
Though it may not be as varied or stimulating as some of the sleeves released after the STU.
This is in comparison to the Fleshlight Ice texture, and a couple of third-party sleeves, by the way.
The fleshlight STU will generally get you off in under five minutes even if you have used it for years.
If you're looking for a first fleshlight, this one is a great place to start.
The Stamina Training Unit is very pleasurable, and some might even say it may be too much so.
But in either event, I would recommend this to anyone shopping for their first fleshlight.
If you're a utilitarian who just wants a quick release instead of a long session, This is for you.

The Stamina Training Unit (STU) was my first purchase with ILF. I had purchased it along with the SIAC Sukit Draft for half the price, but that will be a review for another time. Today were talking about the wonderfully sensational tube of flesh that is the STU.
As a first time FLier I did research as to which product would be the most suitable to my experience as well as my size and boy am I glad that I decided on the STU to be my first companion as we stepped into the world of pleasure that is well, you know..
After many flights with this model, I feel that I am much more able to review what I have experienced thus far.
The STU is a very unique texture not in the sense of the many variations inside the canal that many others provide, but rather quite the opposite in that it offers a sort of linear reliability with it's uniform insides.
The STU is lined with rows of alternating bumps that circle around the inside of the whole Fleshlight. These bumps are spaced fairly close together so when you insert yourself it will feel rather snug and welcoming. Though the bumps feel amazing during the session, I have found that the real magic maker for me has to lie within the tightness of the orfice itself as the first inch or so is able to apply the perfect amount of pressure around the whole of your member. This coupled with the unrelenting massaging of the bumps leads to a very fast, steady and eye rolling buildup. It doesn't stop there, as you get closer and closer to the final countdown, every single bump that is pushing against you seemingly comes alive. As your cock tries to expand it is met with the bump's counter attack of pleasure that will throw you over the edge.
The climax itself is something you will have to experience if you have not, words truly won't do it justice in my opinion.
Now go get cleaned up and rest assured that the STU will be ready again to bring you to that level of intensity where you want and know you will be the next time you get your hands on it.
The STU is a definite must-have for any FLiers new and old as it will be able to satisfy anybody one way or another. With it's uniform texture, you won't have to worry about not being able to feel all of it. The STU will not discriminate. Now what are you waiting for? You have to try to it to be a believer!
The STU was my first fleshlight and took me a few time to get used to it and actually enjoy it. After the break in period it feels great besides the fact that there isn't much variation throughout the sleeve, i have actually noticed an increase in my stamina after using this as you receive constant simulation and its very intensd throughout the sleeve.
This sleeve is good but definitely would recommend other sleeves over this for your first fleshlight purchase
The STU, or Stamina Training Unit, is by far one of the best sleeves in my opinion. It may not look like much, it may look boring, but boy does it feel insanely good.
The description of the STU says that it has been developed for enhancing sexual prowess through training of the ability to control the speed of ejaculation, and that's exactly what it is great for.
The texture is not so intense that you must ejaculate immediately, but it's not intense-less that you aren't stimulated by it. It's the perfect balance between Intensity, Stimulation, Tightness and Penetration.
Once you slide in you will feel many closely-placed bumps that fill up the whole chamber of the texture. Each bump feels great and the deeper you go the greater they feel. The STU for me is like a massage, it's intense but soothing at the same time.
The best way to describe it: an intense stimulation leads you to a powerful orgasm within a few minutes and in order to delay the orgasm, you inevitably have to take a short break or to vary the speed of stroking. This is exactly the skill that you can improve by practicing with the Stamina Training Unit because the control over your own sexual arousal and personal stimulation threshold is the key for improving your sexual stamina.
The Stamina Training Unit is the to-go-to texture I would recommend for newcomers to the Fleshlight world, it's overall a great sleeve with little to say against it!
The Stamina Training Unit, a.k.a the STU, is one of the most loved and hated Fleshlights models around. The idea behind this sleeve is that it is so intense, that if you achieve to last 10 minutes using it, you should last about 20 minutes with a partner. When you look at the texture, it is a series of close "pillows" that surrounds your penis at all times and a slightly narrower canal. At first sight it doesn't look as impressive or as that intense - an initial impression that the sleeve soon proves to be a wrong one.
The STU texture makes itself present since initial penetration and remains present through the whole session, making you huff and puff the whole time. The sensations are uniform along the penis, but the closer you are to orgasm, the tighter the sleeve feels making you to do one of two things: You speed up the pumping / humping to orgasm hard or you slow down to prolong the pleasure.
The orgasm option is easy, the control part is extremely difficult. After just 5 to 10 minutes of use, I had to use all the tricks I know to avoid ejaculating - breathing exercises, stopping humping / pumping the FL, thinking in other things, or even adding lots of lube to lessen the sensations and extend the session. When finally I couldn't hold it anymore, the orgasms with this sleeve were intense and satisfying, leaving me spent and waiting for the next session. This sleeve doesn't want to simulate any sexual experience. Its job is to provide your penis with constant stimulation - and it works as a charm.
Many people hate the STU because they don't feel it as intense as promised. My answer to the complaints is simple: use a thinner lube and go SLOW!
The STU is a very versatile toy, but that depends on what you want. If you want to cum quickly, then using the STU as a stroker works as a charm. Pump this sleeve for 5 to 10 minutes at moderate speed and you will be rewarded with an intense orgasm.
On the other hand, if you are looking to last longer in bed, the STU helps to practice edging and control techniques - be warned that those techniques are easier to do when having hands free sessions. If you are like me, wanting to have long and intense sessions, the STU is kind of problematic. It is so intense that 15 minutes into hands free sessions I felt the desire to cum, requiring me to use a few tricks to avoid finishing before the desired 25 minutes. That variety of uses makes the STU one of the best sleeves from the Fleshlight roster.
As all Fleshlight, the STU is pretty easy to clean - just open a faucet with cold or warm water and allow the running water to flush the interior. It dries relatively fast after leaving it overnight on the open air.
All aspects considered, the STU is a good beginner's sleeve for users with Death Grip Syndrome (DGS), those looking for quick sessions, and those looking to practice techniques to delay ejaculation.
ILF claims this is one of their most intense sensations ever; I am not going to argue. The insert, at its widest point, is the same diameter of the Super-Tight (½”) insert but unlike the ST it contains tons of bumps lining the inside. Now, that doesn’t sound particularly interesting but my yank begs to differ. It feels so good from the first time you slide in there and just keeps getting more intense the closer you get to orgasm. For the reason previously stated, ILF places this texture in a segment all its own, which it truly deserves. Designed specifically to allow you learn how to control your orgasm by building up the intensity as you go along. The intensity increase is not linear, but more exponential. Even with 40 textures released, the STU is alone in how it supplies the sensations. If you interested in buying your first FL or if you want to add to your existing collection, look no further; this is a guaranteed excellent FLight. When you do decide to unload, or when you can’t stop yourself, it becomes even more intense as those bumps caress the tip of your penis.
