That's the point of NTR, so yeah, I don't know why or how people can actually like it. But people do, sometimes so much they'll hate on you for asking them why they like it. Myself, I have nothing against people who like NTR, but I sure as heck don't understand it since I don't think the same way.
My main gripe about NTR lately is that there are so many games or videos that come out that have really good visuals or gameplay and the like, but because they're NTR, there's no possible way I could actually enjoy it. It feels like NTR-enjoyers get a lot more satisfaction lately and makes someone like me, who prefers consensual romance and love in games and videos with no bullshit romantic drama (such as love triangles and NTR and whatever else) feel left out.
