OK guys, this thread has been a LONG TIME COMING.
Me and my friends talked about this when we were about 15 years old (in about 1999) and we just don't get it.
At any 24 hour fitness gym I go to, if I walk into any men's bathroom at ANY TIME, there is probably a 75% chance that a naked old man will be right there, seemingly attempting to show me their junk. What is wrong with the older generation? It's not about us younger men being shy or insecure, but these guys don't just get naked in the shower, they're shaving naked, using the toilet naked, weighing themselves naked, and this is right when I walk into the locker room. Use a towel or at least don't be facing members right when they walk in.
