porn topics 😖

Ladies I have a serious question. Why does so many ladies have a problem with their boyfriend/husband watching pornography? My opinion is I don't care if he watches it, because I watch it & we watch it together. Honestly I understand just wanting to get off then go on about your day/night. Yes if it  started interrupting our sex life id probably say something. But until then I leave it alone:) so what's y'all opinion I'd just like to have a grown up discussion please don't bash others for their opinions.
