I'm 20yo and I used to shower at the gym. I was always trying to avoid the old, big, hairy guys who strutted around the place naked and sat by their locker just looking around. It was weird to me but I tried not to think to much about it. Then one day, one of 'those' types of guys was sitting in the sauna and ended up molesting me. I never told anyone. I don't know why, but it wasn't until a couple days later when I watched this show, about a girl getting raped and hesitating to tell anyone, when the thought of actually telling someone occured to me. By then I thought it was too late so I just kept it to myself. I never saw the guy again, if I did, I don't know what I'd do, but anyways, that's why I wait till I get home to shower and I totally get why other guys do the same.
