How does one act around other men?
Um, wow, I'm not even gonna touch Sunshine's disclosures. Total lack of boundaries may be an understatement. 
Just a suggestion about the whole locker room/gym thing. I never go to the gym because I can't afford it, but I still work out pretty much every day. I've got some free weights (very cheap at a garage sale, thank you) and I go out running every morning, sometimes do things like hiking or biking so I don't get bored. If locker rooms are really so bad, there are other ways to work out so you don't have to make yourself sick with worry.
