Fleshjack Endurance (STU)

The Fleshjack Endurance, or Stamina Training Unit (STU), is the only sex toy of its kind! Although it feels very good (one of the best inserts), it was developed with a single purpose in mind – to help men with premature ejaculation, or the opposite problem, erectile dysfunction.

Available in the Butt or Mouth Flesh jack, this sex toy is designed to stimulate you to the maximum, to pull and suck on your shaft and make you cum as fast as possible. Why? To allow men to use this sex toy to train themselves to prolong and control ejaculation.

With the Endurance Jack, you can gradually try to hold back more each time you use it, after a period of time you should find you are able to last longer. Now since the Endurance Jack is ultra sensitive, when you do have sex with a real partner, there is a very good chance you will last longer, and longer, and longer!

Performance Anxiety will hopefully become a thing of the past! For men with erectile dysfunction not caused by a physical problem, the Endurance Jack may help you gain confidence in obtaining an erection and maintaining it – after you have been able to do so for a number of times, your confidence to have an erection and keep it, will hopefully help you do so with a partner. Keep in mind that the causes of ED are complex so results will vary greatly.
