Everytime I hear people talk about it, they say they've felt that way since childhood, but I don't know if I can say that I have, and that's the biggest reason that makes me question myself.
I was effeminate, but, I never doubted my gender. I would play with my friends in school, but when I got older I would become embarrassed if someone observed my behavior. In high school right now I quickly close off on my conversation if someone else comes close at all. The only transsexual behavior I can think of was around my preteens I considered getting a sex change if I ever became in trouble with the law lol, but I also felt awkward at first when I had to change in front of guys, and when I became a teen I began having issues with taking off my shirt in front of people.
When I first began using an internet forum, I got mad at this guy, so I made a female alias to cuss him out. Then I joined this pointless little forum in another section of the site and identified as a guy at first, but that... I guess "bored" me? I reused my female alias and eventually I never used my former one on that forum again. I constructed a story for her, I'd rather not go in detail because those people from that old forum might be lurking around >.> lol. But part of me began to feel upset that this girl wasn't real, and part of me wished to be her.
When I became older my attitude became a little more masculine, and I was proud of it. I pictured my future self as a well-fit man much more outgoing and masculine than I was now (with many blasian children lol). I started playing wow when I started high school, exactly half my characters were male, and half were female. I never pretended I was female like I did before, if they asked, I'd say I was male, but I'd feel a little disappointed I guess. When I did play female characters, I didn't mind being called she, though I might have acted like I did. But I think 'he' was a little bit bothering.
A few years ago I was reading about transsexuals, and I came across Harisu, an mtf Korean singer. I thought she was gorgeous, I became obsessed a little with her but I kept telling myself I wasn't transsexual. One day I was in gym class I was imagining what being a transsexual at my high school reunion would be like, and then I just crashed in my mind and "accepted" that I was transsexual, which stressed me out. A few days or weeks later, I told myself it was a phase and moved on. Didn't think about it again for a year.
It came back a few months ago, and since then a day literally hasn't gone by where I don't think about it. But also, my mind feels more at ease with my emotions. Before I thought my life was going nowhere and I would just live the way I do the rest of my life. Another part of me questions if I'm just using transsexuality to escape this, or if I'm truly a woman. But I feel that if I did go through with this, I would be a much stronger person than I am right now.
I really want to get this all sorted out in therapy.
Oh and I'm sorry if my typing doesn't make sense.

though the fact that the page kept sliding up when I pressed a key didn't help much with that lol
