Fleshlight STU Review (Stamina Training Unit)
Pros & Cons
This highly-regarded sleeve is popular for both the intensity it provides and for its ability to improve your sexual control.
- Pro – This sleeve is great, as its name suggests, for increasing your sexual stamina.
- Con – Some users may find texture uninspiring, particularly if they’ve used other ‘intense’ sleeves previously.
The Stamina Training Unit, or STU for initiates, helps users improve their sexual endurance. The goal is to help you last longer in bed. While you can improve your performance with any sleeve, the STU has been designed with bumps that provide constant stimulation all along the sleeve canal.
