I agree with Paula. I hate to generalize too much from my own experience, since there are many differences between us all. But still, when I think back to my teen years of crossdressing, I remember vivid fantasies (okay, I admit it, I still have those fantasies) of having a genuine female body, and enjoying that femininity. But it was always totally clear to me that those were just fantasies. I never would have been receptive to any suggestion that I really was inherently a girl, or that I should change my body. And my male parts gave me way too much enjoyment for me to seriously consider giving them up. While there are some unprofessional "professionals" out there (doctors, therapists, etc), and some kids are genuinely confused about their sexual identities, I think there are enough safeguards in the system to make it unlikely that more openness and acceptance (which is a good thing) would result in erroneous transitions (which, of course, would be a terrible thing).
