Before I started HRT and transitioned, I was always the strongest "girl", the most aggressive and weight lifted a lot. If I was able to pass as a male, it would make me feel on top of the world.
After I transitioned, there were moments of realization where I would realize that compared to cis males, I was shorter, not as strong and didn't know all the inside male jokes. It seemed like i went from the top of the pile to the bottom as far as strength and size. I never fit in with females, but the fact that I was far more masculine made me feel good.
After a while, I realized that there were other guys who were as short as me and didn't have the heavy bone structure that I thought of when I thought of a regular guy. After that, the feeling started to come less and less. Now, after a couple of decades, I rarely get those feelings. Sure, I'd like to be taller and have a heavier muscular figure, but I've learned to like myself the way I am.
FYI, I used to look in on sites for transgenders but never sign up. It sounds like that was part of your process as well.
