Shades makes an excellent point. How much of the changes that have taken place within me, would have happened anyway, as a result of experience and so forth? Not all of them, by any stretch. But certainly some of them.
I think I am essentially the same person as I was, because I was always this woman. BUT there have been some sea changes, some expected and some not, some important and some merely interesting in passing.
One big thing is that the mere absence of testosterone effects important changes. I don't think I probably need to catalog them here. And the simple presence of estrogen brings more changes, again well known to anyone who reads these boards.
But i also have gotten a major, first-hand education in what it means to be gay and to be a part of a minority. That experience has made me more compassionate towards many different sorts of people. I'm unquestionably a better person for it.
There are any number of little mannerisms and inclinations that are generally specific to or typical of females, that crept into my own ways one by one, by natural process. Other things fell away. Even though most of my male friends stuck with me when I transitioned, I eventually stopped seeing them all, because we didn't have the commonalities we once had. Almost all my friends are women, now. That's not for everyone, but it occured naturally for me, and I like it. To illustrate the sort of unexpected, not really important, but interesting things that change, I'll throw out this one: my lifelong interest in baseball, my love of the numbers and the history, just vanished. I still like to watch my local MLB team on tv or in person, but i couldn't care less anymore who plays shortstop for Atlanta, or how many homeruns they hit in 2003. I just don't care at all, and I did, before. On the other side of the coin, I've been learning to cook and discovered that I love it. I dodn't do this because it is stereotypicaly feminine. I took it up because I suddenly found i wanted to. Also, babies never did a thing for me, and now I find myself oohing and ahing with the rest. I've gone soft!

So yes, things change, sometimes unexpectedly, and sometimes surprisingly. At least for me, they did.
