Personally, I don't believe our desires to strap on a pair of breasts and pretend we are women or have sex with people of our same sex have anything to do with chromosomes, conditions in the womb or drugs our mothers may have taken, I believe these desires come from events that happen to us after we are born and maybe that should be the subject of a separate thread someday.
But, if we are discussing the possibility of these traits being formed in the womb, it would be pretty unscientific to leave out other traits such as compulsive, anti social or habitual criminal behavior. You can't pick and choose.
