I've only just turned 26 and haven't even begun to get therapy yet, so things like T and top surgery are way down the line for me as of this point. But then, I can pretty easily pass when I don't have to talk, but if I introduce myself by my male name (like to a new person at college or something) they pretty much just file me away as a dude w/ a high voice.
I am sure that once I start hormones, if I ever do, I'll be quite dashing and very happy.
I do wish that I had known about transgenderism and GID when I was young, and just felt completely hopeless being stuck forever in a girl body. But I just didn't know that gender transition was possible back then, I didn't really know about other TG people, or what TG meant, or anything really other than my parents were utterly, completely terrified that I was a homosexual and that they really didn't want me to be "like that".......
But then, there's no changing the past, and no sense in looking at others. One must make do with what is, and honestly in my case I usually find myself thinking "it could be worse".
