I dont think thats much of a factor, ciara the singer has more male hormones than female ones (i hope its not a myth lol) and she's not all mannish. It could affect the way you act to a certain degree at least on an emotional or neurological level but society would form alot of their charateristics and habits... Outside of that aren't that much differences between the sexes except when it comes to gender roles and thats determined by the sex organs/physiology which exist in the way the do solely because of the sex hormones. i dont understand how it would affect thier sexual identity or preference without changing them physically. Sexual persuasion is a matter of choice just some choose to work against nature, which is of course unnatural. Thats why they tend to emphasise choice and rights but basically they're claiming the right to do the wrong/unnatural thing.
