No, it's nothing like "dysphoria." "Dysphoria" is a made up concept, and it doesn't prevent someone from having healthy relationships.

why do you think learning to like female genitalia would be preferable over learning to not be repulsed by men?

Because;

1. The repulse towards men seems way, WAY stronger than one part of the female body.
2. I have what I can only describe as occasional "straight behaviors" that gay men don't seem to have. I find myself wishing I had a female partner and that I could have biological kids, those thoughts come naturally to me, I just can't act on them because sex with women is not something my body responds to, and mentally, part of it causes me discomfort. This level of discomfort also varies. My discomfort with men does not.
3. I do not believe most men are capable of love, what I have seen from the "gay community" is a disaster, and if I have a choice then I am not going to deal with the disaster of trying to find a male partner actually capable of love and dodging all the weird "culture"/stereotyping/toxicity that comes from "the gay community."
4. It's simply what I want. Why is that an issue?

Most people would assume that you just want a healthy sexuality, not a straight one. That is probably why people are accusing you of internalized homophobia.

You have to remember that heterosexuality is the natural and expected for beings that reproduce sexually. Again, why is it an issue if I think that's right for me? I truly believe I wouldn't have turned out homosexual if I had a healthy childhood, and some heterosexual instincts are clearly still in me, so why wouldn't it make sense that this is the healthy option for me?
