Is it acceptable for men to wear thongs?

I have worn them a few times and found them to be quite enjoyable (when you find the right one), but it seems there is a crazy stigma against men wearing anything other than boxers or boxer briefs. I like wearing them and my girlfriend even likes me wearing them. Still, I am concerned and nervous to wear them in public and even more nervous about changing in the locker room. Should I be, or should I just say screw it be proud of my choice?
