Is it okay if I'm a dude who wears women thongs under my shorts during my soccer practices and games?
I see nothing wrong with this. Why do you enjoy it?
I like to see guys reactions when they see my thong in the locker room
I don't think it is very helpful to try and bait people in this way. Is there something else you can do to have fun?
It was a bet.
It sounds like a one and done kind of thing, so what's the harm. You honored your bet and had a laugh, there's nothing wrong here.
