What are some things that will make stories less or completely unappealing?

Hello all! I think there were some posts like this, but i have never seen like a full list or a post where it was actively asked what others dislike, which i'd find quite interesting. Here's my list:

1. Castration: I'm somebody that will really put himself into the male character's perspective and therefore only likes those things, that i'll actually find hot if they happened to me in real life. Threats of castrating someone are usually really hot, but when they actually happen in stories it just destroys the hot part and makes it too much for me. There are some stories where it's somewhat ok though.
2. Mother/son: I can't say the same about this one. Even if sister/brother or even daughter/father stories can be some of the best if they are well written, as soon as there's a mother/son dynamic i just can't stand it. Again, i really dive into the male character's perspective and because my mother always had a normal dynamic to me i just can't find anything hot about it, those stories are just weird to me as i want my own mother to be as little of a thing in my sexual life as it is possible. The same with the dynamic could be said about my sisters. Apart from some thoughts when i was very young i never wanted my sisters to kick me, but for some reason those stories usually do it for me.
3. Fantasy stuff and creatures: I'm usually also a fan of stories that sound believable and relatable enough, therefore fantasy creatures like goblins and witches are just not connected with my fetish. I might be boring in that regard, but even in my deepest fantasies i can't find enjoyment out of non-human characters busting balls as it just makes it too unrelatable. Even if i know that many fantasies of mine won't be happening in real life, they are still always without paranormal stuff and theoretically possible.

I'm not saying those stories are necessarily bad, i'm very sure there are great ones with those topics, it's just not my cup of tea. I don't want to change anyone's opinion or want to set rules that aren't and shouldn't be there, i just wanted to talk about it. Feel free to let me know what puts you off in ballbusting stories.
