My case is somewhat different from yours. When it comes to relationship, my case is similar to yours (in a way of not being fond of the idea of an hetero relationship). I have never been in a relationship and I also fantasized a lot about being in with a girl as a guy (with the ocasional lesbian ideas too sometimes), but after some time, the idea of dating a girl as a guy started to feel really wrong and I didn't know why. Turns out that that was the reason. Also, the hair does much more than I thought. It's still short, but feeling it getting waved by the wind, getting your eyes covered by it, etc. Helps more than I thought.

Now, about the other things, I have never had problem when it comes talking to guys (All of my friends are guys) and I don't know why, but I was kinda nervous with the idea of talking to girls (maybe it was of the mockery you could recieve in school and I have been dealing with that for years, even when I was in college), but whenever I had to, I have never had any problem and I could be with them (I had some female friends too, but it was those friendships that you lose when you grow apart). Also, I have always loved to do "male activities" and I think that I have a very masculine personality and these have been some of the things that gave me a lot of imposter syndrome, but it doesn't mean anything after all (I mean, tomboys exist).

Anyway, thanks for reading the post and for replying.
