As always, I feel obligated to put a disclaimer on the front of this. This is my story, not 'the Trans story'. Many Trans people don't have inklings until puberty or later, and many don't come out until they're well into adulthood; many Trans people don't feel 'trapped in the wrong body' (nor did I, actually - specific parts of my body needed adjusting, but I didn't want someone else's body!) and many don't have any major problem with their anatomy at all; there is no one way to be Trans. There are as many ways to be Trans as there are Trans people. If you are questioning your gender in any way and you don't relate to my story at all, that does not mean you're not Trans. Check out the LiveJournal communities transgender, genderqueer, and newtrans - between the three of them, you'll likely find some folks who feel similarly to how you do, no matter what that is. Okay? Okay.
I'm not going to write my whole sordid tale here - it's more a list of facts than anything else. So I shall put it in list form!
All this really is my experience. I have not modified it to appease any gatekeepers or the Trans community or anyone else, and I can't help it if it's pretty textbook in a lot of ways. My story is valid too, and it needs some air. I'm tempted to repeat my disclaimer here, but you can scroll up and reread it if need be. Your narrative is valid, and so is mine, and so is everyone else's.
Thanks for saying that every Trans person has doubts - EVERY SINGLE ONE, no exceptions - and that those who say they've never had doubts are lying or deluded. I'm not going to post a comment letting you know that my experience doesn't fit with your opinion, because your comment is what the OP needs to hear at the moment, and my refuting what you say is self-serving and counterproductive - all the more so because you probably won't believe me. And I don't need a pile of comments telling me that yes, I am lying or deluded, and I should shut up until I'm willing to admit the truth, because I have a feeling that's what I'd get.
But you know what?
I have never doubted my gender identity.*
I'm not lying or deluded; I never saw a therapist who demanded that kind of narrative from me, or tried to push me in that direction. And lying about my identity has never been something I was interested in doing. I never pretended to feel like a girl or to like things that I didn't like, not for one second. And I won't lie now and say that I had doubts, or times of denial, or that I went through a try-desperately-to-be-'normal' phase, because I didn't.
I have been unsure about whether I wanted to take hormones. I have believed that I was mentally ill because of my conviction that I was a boy, and that I would eventually be institutionalised for it. I have been afraid that I would never be able to be seen for who I really was. I have felt completely, utterly, inescapably alone.
But I have never doubted that I knew who I was. I have never thought of myself as a girl, even while thinking that I must be crazy. (The 'I must be crazy' realisation came at about age 3; the conviction that I was a boy came at age 2, and yes, I remember being 2. Please stop asking me that.) When nothing else made sense and I knew nothing else about myself or anyone else, I knew that I was a boy inside.
I know I'm very much in the minority - actually I'm not sure I've ever heard anyone else say that they never had any doubts, which is all the more reason for me to not hijack the thread demanding to be seen and recognised and validated. But that is still my truth, and in light of a recent post I made, I am airing it. It's just as valid as everyone else's, and I really don't appreciate being told I don't exist just because my narrative is quite unusual.
*Now my sexual orientation - that's another matter. But that's not what this post is about.
