Since I put that I have mixed feelings, I'll write the blogpost here.
I will use netorare and ntr as synonyms here for the most part, because I separate netori and netorase as somewhat different fetishes.
I like some netorare, I used to like a lot more, but during the last year I've been moving away from the fetish to the point where I sometimes return to some of my favorite works, but rarely try out new ones. The main reason for that is a combination of me getting rattled by a couple of works that I got too invested in and interacting with the fanbase enough to realize, that a significant portion of them are people I'd rather not be associated with.
On the whole, I think that NTR is rather twisted and one of the more unhealthy fetishes, which is fine in small doses and when you're a healthy, reasonably balanced person. As it stands now, I'm fine with netorare that is relatively light-hearted or comedic, or that tries to minimize the presence of the protagonist (hitherto known as the cuck, although sometimes he's not in a relationship, just someone in love with the girl), but I've come to despise netorare that is focusing on humiliation and suffering and takes pleasure in the whole process of turning the love interest away from the cuck. I have always preferred stories that have somewhat happy or at least bittersweet endings. While the love interest does have sex with someone else and the cuck suffers emotional turmoil, in the end the relationship is either salvaged or the cuck moves on to a happier place. That is the way how I can sympathize for the cuck and still enjoy the corruption/adultery of the love interest.
However plenty in the fanbase need that unhappy ending (not talking about short manga that only have the sex without any kind of resolution), and they're quite vocal about it, which makes me think that what they enjoy is not the taboo of the corruption/adultery itself as much as the suffering and humiliation that comes with it. There are plenty of sociopaths, women-hating incels, self-hating masochists and sadists in the fanbase. You get comments like "the cuck deserved it for being passive/a beta", ie., he needs to be punished for being insecure, not sexually aggressive enough or having some other personality flaws. You obviously get a lot of 'slut-shaming', despite the fact that, let's be honest, in most ntr women are written in a manner that enables the adultery without much thought given about depicting them as human beings with moral compass and agency. Some say they 'self-insert' into the ntr man, which I guess can happen, but then the thing is, in almost all netorare (not talking about netori or just plain cheating) the bull/chad is written as a psychopath or at the very least unpleasant and sexually predatory, so why would someone 'self-insert' as this character (maybe aside of as attempting a sort of cope). You will get plenty of 'it's just porn, lol', but many times when I have pushed the subject, turns out the person is just as fucked up as they seem at a glance.
All of which doesn't mean that there are not plenty of chill people among ntr fans or consumers that are self-aware or don't really put much thought in it.
So yeah, it all kind of turns me off to ntr now. I still like swapping and some netorase and netori though.
