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.

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.
