This is to no individual in particular. Just a response to the various ideas in the thread.
There are almost no functional differences between my body now and how it was before. I'm a little weaker, I can't pee standing up, etc. Transition, from my perspective, is essentially cosmetic. The shift isn't in how my body works, but how my body looks, feels, smells. That shift, in turn, alters the way that other people react to my body--from increased disinterest in my opinion to my girlfriend's desire to sleep with me.
For me, the primary goal of transition was to convince my brain that my body was no longer "wrong." To shift my self-perception from "monster" to "person." It is hard to describe exactly what I mean by "wrong." But the discomfort was enough to suppress much of my interest in life, as well as a good portion of my identity and personality. To me the pills I take and the surgeries I had were, at their core, the equivalent of a very powerful anti-depressant, with limited negative side effects (at least physically).
I have very little in the way of romantic notions of a natural form. I've spent too much of my life at war with my body in one way or another. I used to have a tag on my profile that said "100% artificial." I can't really bring myself to care that I am "less real" or some such than other humans. To me, I am an improvement over the screwed up mess of a body that I was gifted with. Every alteration to my form, every pill, every surgery, even each tattoo and piercing, is part of my effort to reclaim, recolonize my flesh. This is my body and I will make of it as I damn well please, nah? Perhaps that perspective is because of my disability. I don't know.
As to how I am perceived by my society? I find "woman" to be the path of least resistance. So my name is Sarah and I am legally female. But I would never have transitioned for that. And in a world that didn't offer sufficient tools to alter my flesh, I'd probably be dead now, I'm guessing. So it goes.
As to gender norms and roles and all that jazz? It will be something I struggle with and struggle against for all of my life. There will never be a comfortable place in this world for people like me. Not in my lifetime at least. But at least I am lucky enough to live in a time and place where I can walk down the street without being regularly harassed.
I think, as always, it important to remember that we have more differences than similarities.
