insecurities or reasonable?

I’ve been dating this guy for a year now. All he follows on social media is half naked women who post provocative content….

I told him that’s not what someone in a relationship should be consuming….

He thinks it’s okay as long as he has the discipline not to act on it because he “ doesn’t want to look at men all day”…

I don’t follow a bunch of attractive men and engage in their content so I don’t see why he can’t do the same….

I’m not insecure I just hate knowing he watches girls twerk and show off their body daily…
