The older I get, the more I’m convinced that the line between “art” and “porn” is nonsense created to oppress women and sex workers.
It’s true and OP should say it.
It’s also tied up in classism/educational elitism, and it’s the same reason people claim fanworks, comics and graphic novels, rap, genre novels, graffiti, mixed media/new media works, and video games aren’t art.
Also entirely correct! People use “good taste” as a synonym for “appeal to privilege”, especially for erotic art and literature.
