Just like I find many master's runners pervy, those guys at the gym are beyond the pale.
If you want to shower, fine--go in there, shower, come out, get dressed, whatever.
It's not the fact that they walk around naked--it's HOW they do it.
First of all, they're disgusting. Face it--basically the only guys who look decent above the age of 50--no, 40--no, 30--are gay. They're the only ones who really care, and who make the time to work out. The straight guys are usually totally disgusting, and furthermore, are totally self-unaware.
They're probably unaware of the very fact that they're naked, because their clothes are so awful that they don't make any difference to how disgusting their bodies are.
I know people on this board are runners, and that some are 50-70 yrs old, and are probably not disgusting--but even you guys must get creeped out by those pasty weirdos at the gym.
Whenever I can, I use the teen/boys locker room just to avoid those creeps. Of course, the teen/boys locker room is full of other adults, similarly trying to avoid the pasty naked creeps in the adult locker room.
I think I've posted this before, but at one local YMCA, those pasty naked creeps, after coming out of the shower, SIT AROUND NAKED ON VINYL SOFAS AND WATCH TV TOGETHER!!!
NOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!
Oh My God.
