the problem is at that age, you get a boner easy. Just having a girl rub up on you would cause a boner. how the hell do you explain to the whole crowd when your done you have this huge boner just sticking out like a flag pole. I could see things like Baseball and having boys/girls playing together but anything that involves skin contact is like playing with matches in a closed room with a spilled acetone container
That's actually a legitimate concern I think. I would wrestle a girl, but it would have to be in private
