There is a highly believed myth which states that there are 2 opposite sexes and everyone is either all male or all female. But there are lots of eceptions to this myth. I would even go so far as to say that most everyone has some characteristics and emotional feelings of the sex they are not. Sex, to me, is a spectum, rather than a duality. It is a bi-modal curve in which many people are predominately either male or female. But the curve is continuous, with lots of people between the two peaks. And very few people at 100% male or 100% female.
