Honestly I don't wear either and every gf seems to try making me wear something. Boxers end up giving an awful wedgie, cause a weird fit while wearing jeans, I've tried several brands in hopes its just me... boxers don't fit that well for any wear, I have a flat arse so most begin to fall off if wearing for sleep/house wear
Pants/briefs, only wear them for sports.
Two years ago a gf talked me into field hockey practice with her friends, borrowing undies was the most embarassing moment in my life
heh, should have acted like a Scottish person and not care if someone got mooned... buwahahaha
