There sure is a loud amount.
I would really be curious, how many really do dislike ntr so much, as in statistics. Problem is, that many call stuff ntr, that ain't. And also, there do be self proclaimed ntr games out there, some of them very popular. Actually, when I think about it, I encountered only one real ntr game so far. The rest was just people calling stuff ntr, because there is more than one dick in a game.
