Eh, it happens, Jesse. I didn't think about transmen when I first started transitioning, though I had known one before I had even known that I was ts. When I first started transitioning, I was way the heck up north, in a very rural area. There were no other transfolk around there for support, though there were some that were there, in stealth mode, from what I was told.
Transmen didn't really come into my consciousness until I moved to Houston, and started hanging out at the TG Center here. Then I started learning.
