You're incorrect in a lot of ways. But it's not about being surprised that "some people might have problems with how popular the genre is." Being sensitive to NTR is one thing, but I've seen people say sex toys don't belong in a harem, and that is really concerning. I'm not trying to ridicule anyone or do any kink-shaming whatsoever, but you really must know this extreme aversion is not normal sexual behavior. And I can't emphasize this enough: some of these remarks truly worry me, and I think those who are experiencing these types of anxieties ought to get help. It's not normal. Of course, the severe fetishes on this site are likewise abnormal, but most people are already aware that these fetishes have no connection to reality. And sometimes exploring these can be somewhat healthy, within certain boundaries. But sometimes I have the feeling that people with extreme aversions towards NTR also have extreme and/or distorted views about sex in real life.
