This Tragerbody (I think) bodysuit from Tendenze is the sexiest thing you can wear to the gym. It is very revealing, in that your junk bounces around so much in the separate pouch, and the material pulls up nicely up your ass. It's also a nice thin material that really clings to you. And it leaves your chest and nipples nicely exposed. So if you are laone in the gym of course you are going to play with yourself!
