Sadly there is so much badly delivered NTR you can't blame people for misconception that NTR sucks. Its like 99.99% lately is divided between or combining woman is raped and woman becomes a brain dead cock addict.
Part of the problem is that NTR has overlap with several other fetishes. Most people aren't introspect enough to be able to separate NTR from the specific fetish they like that has overlap with NTR, but isn't actually NTR itself. So, they just think they're into NTR itself. Meanwhile, NTR's got a lot of hot-button controversy around it. So, tagging your game with it is an automatic way to get eyes on your game.
Queue people who just like rape, corruption, or cash making shittons of NTR stuff without understanding/caring what NTR actually is and just kind of slapping it in there. It getting like two textboxes at the start to establish she's got a boyfriend and then right into generic-as-fuck rape or corruption story. Those two textboxes may as well not even be there.
Meanwhile:
Words are defined by how we use them, not by what we say the words mean + NTR's overlap with so many things + Urban Dictionary trying to dictate the meaning + NTR being a collection of 4 separate fetishes = People constantly arguing about what the fuck the term actually means.
Note: Yes, 4 types of NTR. Urban Dictionary says its 3, but Urban Dictionary is wrong.
I literally have the 4th one as my NTR fetish. UB can be fine for western slang at times, but its fucking dreadful for anything that came from a country that doesn't speak English.
