I believe there's misconception about the NTR genre. People tend to think that ntr enjoyer would like to be cucked or at least would like the idea of being in that situation themselves... when in reality, I do believe the reason they enjoy it is far more degenerate and worse, depending on how you see the situation.That's because most people think NTR is the same as cuckold , which is not always the case.They do have similarities , but since it's the only english word close to ntr, people tend to think they're alike.
Netorare is focused largely on the fixation of loss, the pain of having someone you love (even if it is not reciprocated or codified) taken away. So as long as this requirement is fulfilled , regardless of the pov , main protag , and story , the game is considered as ntr.
Anyway, the problem here is , some people are not really informed about the genre in general, leading to a lot of scrutiny and unnecessary discussions.
People tend to think NTR is for masochist, people that like to suffer, but I do believe its actually the complete opposite. NTR is made for voyeur with heavy sadistic tendency. People that get turned on by observing a situation unfolding in front of them, of a pathetic man loosing everything he loves on one handle, and in the other, someone that was supposed to be pure, getting sullied and corrupted by their own lust. What turned people on, when you actually read the comment on NTR game, is the despair that come out of these situation, the breakdown of 2 people that generally are happy to start with but slowly but surely descend into hell.
It does remind me of the incest fetish. In most case, its not what people think it is. No one actualy fantasize about fucking their own family. What turn on people is actualy being made into a voyeur, witnessing the breaking of the universal taboo by others.
