Fleshlight pink lady stamina training unit - masturbation sleeve by Fleshlight - review by Carodenius

The STU Lady is the second Fleshlight sleeve that I have tried. The first one was the Speed Bump. STU stands for 'Stamina Training Unit'. The sleeve is meant to either help you build up your stamina or to make you orgasm in record time.

A Fleshlight is a masturbatory sleeve enclosed in hard plastic casing. It is meant for males. It can be used alone, or enjoyed together with a partner. Fleshlights are a good way to spice up the session.

The Fleshlight family is well-known for its good quality and unique texture, which many other companies have tried to replicate. I was already used to the feel of the superskin and was more interested if the STU would feel more intense than the already-intense Speed Bump.

The case is made of very durable plastic which you can get in different colors. The Stamina Training Unit I'm reviewing has a golden case, which makes it stand out a bit more than I'd like. The plastic case has three parts. Both end have caps can be screed on and off when needed. This makes the toy easy to disassemble for cleaning purposes. The third cap is used to control the suction of the toy.

The penetrable sleeve, itself, is made of superskin. The material can be stretched out quite a bit and will always return to its original form. It is very very soft and gentle. The outside feels smooth, but slightly sticky if you aren't using lubrication. The sleeve can be used with water based lubricants. With a little drop of lube, the toy becomes very slick and enjoyable to touch.

Superskin retains heat very well and can be heated or cooled by placing it in warm or cold water, respectively. I highly recommend everyone to warm their Fleshlight sleeve and lube before use.

The sleeve itself is very spongy and soft. It is softer and has less resistance than real skin. You can use it without the case. In this case, however, you will struggle to keep the flimsy sleeve in a good position without external support.

The inside portion of the sleeve is filled with very intense bumps. As the name implies, it is meant to be a training unit. The feeling can be overwhelming for some. Some people actually have to stop mid-session because the sleeve can cause chafing without enough lubrication. If care is taken to use enough lubrication, however, the sleeve is very enjoyable. Keep in mind that lube needs to be reapplied several times during a session, which can be slightly off-putting.

The outside of the sleeve is made to look like a vagina. It is very well made and the soft material makes playing with the lips an enjoyment of its own. The case is quite large and people with small hands won't be able to wrap their fingers around it entirely. The plastic case can also get slippery with lube. This can be circumvented by placing the toy between pillows and using it hands free.

The case protects the toy very well while it is kept in storage. For long storage, it is recommended that you sprinkle some powder into your sleeve to keep it from getting sticky. Prolonged contact between the sleeve and other materials can cause discoloration and other issues. This is why it's recommended to keep the caps on when the toy isn't in use.

The plastic case is very sturdy and can be placed in a suitcase or backpack while traveling. It is slightly too large to be truly discreet, though. It is slightly larger than your average handheld flashlight.

The toy doesn't have any vibrations on its own. You can, however, order bullet vibes from Fleshlight to give the Stamina Training Unit even more 'oomph'!

The sleeve attracts a lot of hair, lint, and dust, so make sure to minimize its contact with fabrics and the floor.


The toy is very easy to clean. You just need to unscrew its back end and rinse the sleeve with water. Let it dry completely before closing it. The stretchy material makes it possible to turn the sleeve inside-out if needed.

The toy is packaged in a very brightly-colored Fleshlight metal tube. It isn't very stealthy or discreet. I would call it the Pringles can of the sex toy world. I really wish Fleshlight made their packages a bit more regular-looking.

My experiences with this toy have been varied. It is a great toy if you are looking for something very intense and tight. The constant need to add lubrication is a hassle, but sliding in and out of this toy feels pleasurable enough to ignore this inconvenience.

Both ends of the toys can be penetrated, even simultaneously with a partner. They toy makes a lot of slurping noises, so it isn't very discreet in sound if you enjoy a faster pace. Having a slower place diminishes this issue somewhat.

My partner complained of chafing. He had to stop using the toy mid-session due to this. We used the toy together later and, after I took applied a lot of warmed lubricant, he enjoyed the toy a lot more.
