When you embraced and expressed your trans identity, how did you process that in terms of your sexuality?

So if a heterosexual born as a man is trans does she think of herself as a lesbian, or do those categories no longer apply? I'm gay, so I'm attracted to other men. It doesn't really matter to me what my gender is, I'm not attracted to a sexuality I'm attracted to a person, so I think it I were trans I'd be straight technically because I'd be a woman attracted to men, but I've been gay so long it would be challenging to see myself as anything other than gay even though I'm not expressing that sexuality in my relationships.

I'm guessing the answer is something like "none of the above" but I'm just curious. It was just something that occurred to me and I was wondering how it plays out.
