The Fleshlight STU (Stamina Training Unit) is exactly what it sounds like — a purpose-built endurance training device for people who want to last longer than a SpaceX booster stage. The internal texture is specifically designed to be more intense than the real thing, so when you finally dock with the space station, everything feels like easy mode.

The concept is simple: train at a higher difficulty so the real mission feels effortless. The STU's internal canal features a tighter, more stimulating texture than standard Fleshlights, helping you build control and extend your countdown timer. Fleshlight even includes a training guide because yes, this is that serious.

Made from their patented SuperSkin material, the STU feels remarkably realistic while being easy to clean and maintain. It's the difference between a cadet who panics during re-entry and a seasoned pilot who stays cool under pressure. Your call, space cowboy.
