I've only done that in one instance but it wasnt even in the locker room, it was in the shower @ school after wrestling practice. Even though its a wide open shower, the only light comes from the hall way leading to the shower, so i dont see it as being gay at all.....unless some dude walks out w/a boner...

In the gym though, I take my boxers w/me to the shower and hang them while I do my thang.
