Well... I'm an old man now.

But I struggled with gender identity dysphoria for my whole life (MtF.) It's only quite recently that I feel like I've finally come to terms with it.

One of the most confusing parts of it has always been that I was completely heterosexual. I never had any sexual interest in men. In fact I've actually always been quite uncomfortable around other men.
The current theory, I believe, is that gender identity & sexual orientation are established in utero at different points during the development of the fetus. Consequently it is completely possible for a person to be transgender but at the same time to be sexually attracted to members of the sex opposite to their assigned gender at birth, if that makes sense.

Assuming that is in fact the case, then it's really nothing you (or I) had any control over. It's just way we developed way back before we were even born.
From my perspective, I think the answer here is probably to spend some time working with an experienced gender therapist. I do think it's important to work with a therapist who is experienced in working with individuals who have GID issues. A therapist who is not experienced with, & interested in, these concerns can do more harm than good in my experience.

In fact, I think spending some time seeing a gender therapist is probably important for most transgender individuals regardless of whether they have sexual orientation issues or not.
By the way, there are a couple of YouTube channels you might want to check out, if you're not already familiar with them. One is gender therapist Dara Hoffman-Fox's channel. Here's a link:

The other is The Transition Channel:

I wish you well...
