No.987
Guys getting dumber every time they are being fucked, sometimes the effects are permanent, sometimes not (It depends on my mood).
It eventually evolved to a brainfuck fetish, but since I rarely see yaoi of It, I usually dont indulge in this version of the fetish.

Dunno how /ex/ this is, but I like this specific scenario where the character and his loved ones get kidnapped, and the kidnappers rape the guy while forcing his loved ones to watch. I also like if one of the other captives (could be a family member/friend/lover/etc.) volunteers himself instead, and now the guy that just got raped has to watch one of his loved ones get raped too.

Diapers? I know that's a cringe one for a lot of people and I don't like much of the art featuring it myself, I only like it in writing tbh. I like that's it's deeply embarrassing, especially on very mature feeling characters taken out of their mature, cool/sleekness.
I love eating disorders and adjacent stuff as well. Sexual situations with purging, and anorexic male characters trying to be coy about it
Both are connected by an enjoyment of crying, age regression, and embarrassment/shame I guess.
There's more but they're based around het stuff and thus don't feel very relevant here
