I don't really mind being naked with other men (wink, wink, nudge, nudge) or seeing other men naked but like Flipmo said, it must not be overdone. No wiggling or sackbouncing, and no extended conversations in the nude when you could've put your boxers on and off five times already.
But Chronny, how the hell did you come up with this topic? You don't do any sports, do you?
