I used to find gay man-man kissing (or any form of intimate touching between males, really) very gross despite a very strong conscious understanding and notion that it was just as "right" for them as between a man and a woman.

Then, as I noticed and saw more of it, it got normal.

I don't think so. I think that everything vile, disgusting, and repugnant got normal, not just gay sex.

I say this from observation of people who have conditioned themselves for a politically correct lack of disgust reflex. They also have a non political lack of disgust reflex: Observe, for example the "no pressure" video, and the cannibalism video

I predict that you are also no longer disgusted by poop eating, cannibalism, or the malicious infliction of painful and destructive injury.

I predict that if you watch the "no pressure" video, or the cannibalism video, you will wonder what the fuss was all about.

Someone who quite genuinely does not find feminists disgusting, is likely to be sincerely astonished when lots of people who piously pretend that they do not find feminists disgusting react with outrage at the "no pressure" video.
