Stamina Training Unit Fleshlight sleeve review

Golden classic for improving your stamina

The Stamina Training Unit is a very special Fleshlight. This fact is already visible when holding it in your hand, because the color of the case is gold. At the same time it is one of the oldest ILF Fleshlights. The name of the Fleshlight is also its goal. It tries to improve your sexual endurance, by adjusting you to a high stimulation that is above the stimulation of a real vagina. The goal is to make your erections last longer before you come. Therefore especially men with premature ejaculation problems are targeted by the Stamina Training Unit.

The STU sleeve is available with the Pink Lady (pussy) and Pure (neutral) Orifice. Additionally the Fleshjack series offers an Endurance Jack Ass Fleshlight, which uses the same texture.

One chamber with multiple bumps

The STU uses only one chamber with an unchanging texture. It starts after about 1.2 inch (3cm) and stretches until the end of the insert. The texture consists of large rounded bumps, which completely fill out the inner channel. With a diameter of 0.47-0.59 inch (12-15mm) the channel is considered rather tight, providing additional intensity.

These bumps establish a rather large-area pointy pressure, similar to fingers that press sideways on the penis. The high amount of bumps paired with the tight diameter provides a firm and highly stimulating intensity sensation. Withstanding this resistance for long is hardly possible, especially for newcomers. Therefore the orgasm will not keep you waiting. But this also creates the attraction of the STU, because eventually improving the sexual endurance is the goal with every new try.

Highest intensity of all - helps to improve stamina

Just after sliding into the STU sleeve, the first bumps reach the penis head providing a firm massage effect. This stimulation is not going to stop until you come and finish your stamina training. The reason is: these bumps fill out the whole inner channel of the STU. Every bump continues to rub and stroke your penis, massaging its entire surface with a gentle pressure.

This intense stimulation of the bumps drags on for the entire masturbation and impressively puts the stamina to the test. Resistance seems futile and the orgasm will not make you wait. Although the STU only provides a little variety, suction effect or realism it does its job in a highly effective manner. The key is just purest intensity in order to create the provided stimulation and the STU fulfils this exceptionally well.

The straightforward construction with the unchanging texture also does not limit you to a specific penis length in order to provide the best experience. If long or short penis, it does not matter with the STU. Every length will be put to test just the same. It is the ideal test equipment if you want to increase your stamina or simply love it intense.

Tips & Tricks

Due to the high amount of bumps and the resulting interstices a thorough cleaning is important. The resulting dry time is also higher because of the same reason.

If you want to improve your stamina try counting the time it takes you to finish. Do this for the next multiple orgasms and you can compare the results, in order to see the improvements. Especially in the beginning coming fast is not unusual because the stimulation of the STU is just so high.

Circumcised men often have the problem that their penis is not as sensitive as those of uncircumcised men. By using the Stamina Training Unit you will still be able to enjoy a strong stimulation as well. So if other Fleshlights are not intense enough for you, the STU is the way to go.
