It was for a long time. I never fully believed that surgery, hormones, and attitude made me a woman. I can certainly act the part and feel comfortable as a woman in a way I never did as a male. Nevertheless, a nagging doubt about "really" being a woman persists. The fact that medicine is unable to explain the transsexual phenomenon doesn't help. Theories that we have "female" brains and all that remain theories. I don't doubt transsexualism. I just wish it didn't look so much like a mental issue. Belief alone does not equate with fact and this is one of the dilemmas of being trans. We can believe we are woman and yet those around us can decide that we are not by virtue of birth, genitalia, genetics, etc. Both views are equally valid. You can decide that other opinion doesn't matter, unless of course the opinion is held by a spouse, friend, parent, child, prospective employer....
