Hey guys, I notice a lot of fit guys in the gym showers seem to have nice plump soft cocks (sorry if that sounds silly) while most of the non-fit guys are shriveled up like they just walked in from a snow storm. One of my buddies said that jocks like to keep semi-errect in the locker room to show off a bit. I was just wondering if any jocks/athletes can provide some insite. Does working out increase the blood flow to your cock? Or do you just like to show off? Just curious. Thanks guys.
