I can't say I have. I'm not exactly timid to be naked in front of other people, but I don't really particularly enjoy it and I'm sure everyone around me does no enjoy it either.
When I used to go to the gym one thing I found funny is how people just use the locker room as a place to have conversation. I would get in, see people standing around naked, talking, I'd find a locker, change, put my stuff in it, and go on to work out. Come back from my workout and those people are still there talking. Like, did they even actually go work out? lol. I bet they forgot what they were there for and eventually got dressed and went home.
