it's completely normal to not want your partner to watch porn
there was a tweet going viral of some girl saying she didn't want her bf to watch porn and people were calling gen z 'puritan' and saying that it's 'abusive' to not want your partner to watch things like that. i disagree heavily; and i think it's completely valid to consider porn a form of cheating. if you and your partner are okay with it, then it's fine i guess. but i think a lot of gen z women grew up in the first generation where it was normal to have porn on demand, wherever you wanted it, completely free, and that has affected Gen Z men and what they expect during sex and what boundaries they have. i don't think this is 10th dentist in real life at all, but it for sure is on reddit and maybe twitter.
