Dysphoria? Idk. I never wanted to be the opposite gender because I genuinely could not conceive the possibility. Not even in a fantasy way. I just was told im a boy, was forced into the role and that was that.
Something inside me knew and always picked girls in games, was fairly feminine until I just felt like I had to suppress it. Again, not consciously. Just gradually I became more genderless in a sense, by abandoning any personal identity. The only gender I experienced was forced on me by haircuts and clothing picked for me and whatnot. But I didnt feel anything from it usually, at worst I felt bad.
I suppose I felt dysphoria around 15 or 16 though, in a way. Idolizing femboy characters and wanting to be them but feeling I would never be cute. Turns out I was cute and capable of so much more. But it took until I was 23 to actually realize it. I also coped through my teens with "im not trans cause trans people know when theyre like 5 or whatever"
Im comfortable with myself now but the void, the depression, it was all so bad for so many years and I had no idea why I felt that way. I just knew every second was torture and that I had absolutely no connection to myself. I would look in a mirror and feel nothing at all. Just empty.
