Hey there David! To be honest, that's kind of how I felt my whole life. Not really unhappy with my body, but also I would have preferred a female body if I had the choice. It was only a little bit ago that it turned into more of a dissatisfaction with my body and a strong urge to transition. That might happen to you, it might not. Like Jackie said, there are a lot of different gender identities put under the umbrella term of "Transgender" so it wouldn't be a bad idea to investigate those. We have a
Queer Dictionary here that you should definitely take a look at.
I wish you the best, if you want to talk more about this, you can always
PM me.
