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.
