I watched a science show on that on T.V. My science teacher also went into this.
If you ask any scientist/doctor who are expert on this issue they calim that most of it is actually psychological. This psychological issue derives from childhood behavoir. Most men actually feel that way because they never had a Father figure around to teach them how a boy should transition into a man. So thefore the boy clinged on to the mother and picked up the female like behavoir and it was hard wired into the deep consious.
On the other hand, on some uncommon cases, it is possible to be born a half male and half female. When I was taught this, the scientific evidence was quite clear. For some women, they felt that they always were men. Its because their cliterous developed longer than it was supposed to. Due to this, the female would have the looks of a female but would have the behavoirs of a man. For instance the woman who I read about, when she was young, she always played rough with kids her age (i.e wrestling, boxing) and as she grew she started to act more and more like a male even though she was surrounded by females.
For men, its about the same thing.
But like I said, its mostly psychological. However, there are people who are born like that. I an't rememebr the scientific name for it but people who are half-male and half-female existed since the beginning of time. Its recently that scince is actually backing it up with evidence.
