The fact that you only equate sex/nudity to porn reveals a problem. People today can’t associate sex/nudity on a screen as art, or even just fun, anymore - because in their minds sex/nudity is inextricably tied to porn. The reality is sex/nudity can be fun, dramatic, scary, or funny depending on the context. It can have a place in many kinds of stories, and comparing it to porn is like saying “we have war documentaries so we don’t need war movies.” They are completely different things!!
It’s disturbing to me that we’re culturally encouraged to find fun in violence but sex needs to be cordoned off to a containment genre and excised from mainstream art.
