asheh, you sound just like me, lol.
It took me until I was 20 to realize that I am trans. I started going online when I was about 15 and I always posed as a guy. I couldn't figure out why. It's like, I always knew that I wished I could have been born a guy, but I didn't think I was trans. I thought to be trans meant that you had to be miserable with your body and get nasty surgery to change it. I didn't want to do any of that.
But I've realized that all that being trans means is that you don't feel quite like the gender you were assigned at birth. And that's exactly me.
After I accepted that I was trans, I knew I wanted to dress as a male. but I still didn't know about T and surgery and such. And, like you, I didn't really have dysphoria about my body. That really confused me. I felt fine with my body, I just wanted other people to see me as male.
However, eventually, I've started to change. Now, things that are the MOST obviously female about me, like my voice, really bother me. I feel embarrassed about it. And I just really want it to be different. This is when i realized that I want T.
I've also heard many trans people reporting that dysphoria can get worse over time or change over time, so something that maybe didn't bother you, starts to bother you.
and I'm afraid that's going to happen to me. The more I want to be seen as male and can't, that causes a lot to bother me.
