Thanks everyone. No time now, but I wanted to add, I know some people who were born with traits of either, for example a man who was born with both female and male parts. He's in his 60's and not healthy. Back then, all they did in a case like that was construct a girl. It was easiest. He was raised as a girl, but even without testicles became a man at puberty. I have no trouble seeing him as a man, although he isn't healthy enough for surgery to replace what they took from him. He has a beard and a deep voice, looks and sounds like a man. My daughter's friends aren't so obvious.
