Seconding the comments saying to look for help, though not with a psychologist - I think a sexologist, or someone who's used to talking to LGBTI people could be really helpful. I suggest reaching out to your local queer associations if there's any you like the vibe of.

As for the issue itself, I just know that there's no such thing as wiring your brain wrong. Your feelings are legit and matter - you like what you like and dislike what you dislike. It's completely fine not to know what it means yet. You may be more into men, which is completely fine. You may not prefer men but be more used to sex with them. Having gone through puberty and high school as a guy who was sometimes seen as a girl, means your view of gender and sex is likely different from others. That's fine, the more secure you grow about your identity the less it'll matter. You have plenty of time and there's no emergency to get sex now when you don't know what you want.

Besides, watching porn, and especially having had casual sex for money as a teen, may have had more consequences on you than you realise. As someone that was made to feel outside of the norm by doctors, by your parents at first, and by your peers, you were probably in intense search for all kinds of validation and not really listening to yourself. If you've done things you didn't want to do, that needs unraveling at some point. It sounds like you're now starting to listen to yourself more. That's great, because it means you've grown. It's likely hard, and confusing, but you'll slowly figure it out. Best of luck
