Children taking hormones to change sex is madness. It shouldn't matter what's between anyones legs, if everything functions as it should. Sexuality is such a complicated thing, and not something children should be thinking about! If it's not about sex, then it's about personality? If you love make up, clothes and are dramatic or emotional, you must be female? :S To me being female is about hormones, instinct (maternal and otherwise), contraception and pregnancy worries, menstruation, misogyny, dealing with misogyny, male agression and violence, harassment of all types, power and control issues like coercment and rape. Biology, and bigger issues that need to be addressed, that affect men too. Expectations from society and family. No boy or man can know what's it's truly like to be female, because they aren't. They can become a crude approximation, but that's it, (and vice versa of course!).
