Every embreo starts off as a female in the womb. But the hormones in that sperm will then determin whether the baby grows a penis or fully developed into a vagina. ever noticed how the mens balls look similar to the inside of the female reproductive system? sometimes the hormones can be very close to male and female so close it does both, or can make the person attracted to the same sex.

It doesn't. X = female Y = male The male sex cell has this combination: XY The female sex cell has this combination: XX The embryo gets one from each parent, So XX produces a girl, while XY produces a boy. Obviously (you could draw a chart) there can be no YY.
