If you don't like onions but you go out of your way to keep eating onions again and again, you will end up liking onions.
It's morbid curiosity, the thrill of reading something you see as "bad" and "immoral", at the end of the day you're still seeking it out.
I don't like ntr or cheating stories, so what do I do about them? Ignore them, they don't exist in my mind, if a character in a story I'm reading cheats, I drop the story and never look it up again, that's what not liking something actually is like.
Saying that, I love this author, it's never boring with them, I'm already at the edge of my seat to know what will happen next.
