I never felt comfortable exploring my attraction to men as a female. I felt more jealous and uncomfortable whenever around them, though the latter isn't just because dysphoria/trans reasons. This was back when I didn't know trans people existed, though. Tbh, I just don't consider male = penis, and female = vagina. I know it's normal to, even for trans people, but my attraction doesn't lie on genitals. It may have when I didn't know trans people existed, because my jealousy got in the way of everything, but after that, I never focused on gender = genitals.
When I first realized I was trans, I was still uncomfortable, but I found myself feeling better about saying I liked men and imagining myself being with one.
At one point, I heavily repressed being trans and found myself dating a boy. It wasn't uncomfortable. I trusted him a lot. He's trans, though, so maybe that had something to do with it? I wasn't jealous of him for his body, obviously, and the discomfort wasn't as bad as it was with bio males.
When I started accepting that I'm trans again, I found it easier to explore my attraction to men. Still had (and have) the same boyfriend. I think being with a bio male would make me uncomfortable still because I cannot transition yet. Perhaps I'd feel better about it once I can.
In short, I just have really messy problems, but I definitely like guys (I consider myself bi), and I'm a guy.
