Basic biology tells us about XX and XY. What if there are different degrees of X's and Y's ? If a man has higher degrees of X's than Y's, is it then possible for him to lean toward the feminine side, depending on how much or little of each ? That could explain the different degrees of CD etc. Just something that crossed my mind. How about some of the Biologists on here... I know this would go beyond my high school diploma, so I thought I'd ask.
