Fleshlight Review: Stamina Training Unit (STU)

The Fleshlight STU, or Stamina Training Unit, is designed specifically to overstimulate the penis, with the aim of helping the user improve his sexual stamina and last longer in bed. It is recommended to men who would like to learn to control their ejaculation, or those who prefer a very intense Fleshlight.

Sleeve and Texture

Fleshlight Stamina Training Unit

The STU is available with a choice of the ‘Lady’ pussy orifice or, for those who prefer to keep it simple, the simple ‘Pure’ hole which does not attempt to imitate a real orifice.

The sleeve is fairly simple in design, with just one texture and a regular width all along the canal. It is one of the tighter Fleshlight sleeves, with a width of approximately 0.6” (15mm), and is lined along the whole length with rounded, raised bumps.

These bumps are densely packed and surround the penis on all sides. Once you are inside the sleeve, there is simply no escape from them.

How the STU Feels

As the name suggests, the STU is very, very stimulating. The bumps surround the penis from all sides, and all along the length, so the stimulation is continuous and never lets up at all. It’s like a massage from all sides at once, with tiny pressure points that become more and more pronounced as you move towards orgasm.

I could not last long in this sleeve; it was too stimulating. The orgasm was great but it all felt a little too fast and intense.

This Fleshlight was designed for a purpose, and I’m convinced that it would help a great deal with increasing sexual stamina and reducing premature ejaculation. If you are using this sleeve for this reason then you will need to stop and start a lot in order to control your orgasm – it really is that stimulating. By using it regularly, gradually increasing the amount of strokes and perhaps withdrawing before ejaculation, I’m sure that it would make longer lasting real sex a lot easier.

Fleshlight STU Texture

However, as a masturbation sleeve I found it a bit too intense. With this dense bumpy texture there is no room for a long, slow build up and, post orgasm, it is over-stimulating to the point of being almost painful. Definitely fun to try but it will not be a regular use sleeve for me.

Cleaning

The densely packed bumps mean that this sleeve needs to be carefully cleaned to remove any leftover lube. Fast running water, run through both ends of the sleeve, should suffice. You could also fill the sleeve with clean water, covering the ends with your fingers, and swish it around to remove any stubborn residue. Dry in a warm spot (never directly on top of a radiator) for several hours before putting your Fleshlight away.

How I rate Fleshlights explained

This Fleshlight is made to overstimulate: ideal if you want to learn control and improve your sexual staying power but less so if you are looking for a fun masturbation sleeve for regular use.

What comes to training your sexual stamina, STU works but it’s also a kind of marketing gimmick as any Fleshlight masturbator will improve your stamina if you’re able to stay in control and stop when getting too close to ejaculation.
