I may or may not be wrong, but I'm pretty sure this is about semantics and semantics screwed me up, entirely.
Let's just say that if the me of 1983 had been 10 years old today, I would've transitioned several years ago. Times were different. The me of 2000-2002 did not identify with the statement "man trapped in a woman's body" and I let my first gender therapist know in 2003. It may be my own perfectionism and my own ability to see my body as what it is (I've always been a weakling, but I still have a typically male structure). As a child, I, like others, prayed that I would magically change into a girl the next morning and was always disappointed when I didn't wake up with a new body. The earliest evidence of what I would turn out to be was told to me by my mom's sister after I came out. She told me that I used to go through visitors' luggage when they visited my parents' house and I would always pull out women's and girls' underwear...I was 3 years old, she told me. She only mentioned underwear, so I don't know if other articles were involved (stockings, skirts, etc.). I'm pretty sure I didn't have a sexual fetish at 3 years old.
Later, it did scare the hell out of me that after I reached puberty I did get aroused when I wore women's lingerie. By what I'd read in just about everyone's stories online (once it became a thing), it seemed the gatekeepers kept a watchful eye on such things and people that did feel arousal were automatically labeled ->-bleeped-<-s (DSM-IV 302.3). I came to realize later that these feelings derived from my desire to be seen as a woman in every respect and as a highly sexual (read: horny) teenager and young adult, that extended to me wanting to be seen as a woman to my partner, as well. I do know that I snuck into my mom's and cousins' clothing from an early age and even snuck out of my house late, late, late at night once as about a 10-year-old in my mom's culottes and blouse and probably hose and walked several blocks around my neighborhood. I was, of course, embarrassed, but I was happy at the same time.
Semantics. No, I didn't know I trans because I didn't know the word. I didn't feel like a woman trapped in a man's body, but I did know that I should have been born a natal female. All I'd heard was ridicule of ->-bleeped-<-s and ->-bleeped-<-s and all from an early age, so, yeah...I waited until after I'd already married and the Internet was invented to start researching this and waited even longer to transition until I was 29 (earlier than a lot of people at the time, and for that I can only thank the invention of the Internet and earlier pioneers that were braver than I could ever have been to do so without the resources I had). So yes, if I were ten years old today, I would already be living my authentic life. Well, I'm almost there again after purging for a couple/three years or so, but I damn sure would have a different body structure and wouldn't need to practice my stupid voice!
(Sorry, another long post. I did read and was ready to respond to the poster earlier, but they appear not to be here anymore. I hope, for their sake, that it's not for the same reasons I told a local gender clinic before I transitioned that I would not give them a reason for canceling my appointment as I was too embarrassed that I was going back in the closet).
