I would never do that. But I already know why. He has the personality that makes girls get wet down there. I don't. It is likely a result of his just being "faster mentally". His attempts at social interaction have always been successful so he ended up developing confidence. I with my slow processing speed always ended up being punished whenever I would put myself out there socially. So I developed a timid shy personality. That is all there is to it. Either I need to make my personalty more like his or I need to make sure he never comes near girls I am interested in and generally stays out of my social life.
