I love wearing singlets only to the gym, especially the ones that get a bit see thru hen I get sweaty. Like htis bright yellow one from the guys at Bumchums in Yorkshire. Here's a video showing off the singlet, then peeling it off to be naked at the gym - which I love to do when nobody is around, then putting it back on and trying it out as a thong backed singlet. I hope it makes you horny.
