But I do worry about how what sex acts are depicted as normal might scramble our interpersonal relationships. I worry about how implausibly beautiful people might damage our self-esteem. And the increasing integration into "endless scrolling" with a social aspect and the clicky-clicky dopamine feedback cycle is the death blow.
Most of these concerns are close to nil with an erotic short story, by comparison. To brutally chop this down to a simple idea: Monkey see, monkey do. Monkey think abstractly through imagination, monkey imagine but not see and so not do.
After all, don't you think it's telling that, while teen girls are hooked on the image-pornography of fake stardom lives on Instagram, and teen boys are hooked on OnlyFans content and half-clad Twitch streamers, that there is (to my knowledge) no epidemic of compulsive erotic story writing and reading to go with it? Oh, I'm sure some people do spend 12 hours a day at that, but it seems not to tickle our brains in quite the same way. Such things are merely sporadically titillating, not horrifically and compulsively addictive, at least for the typical person.
Maybe those artists sacrificed something too, but I don't see how it's any different from any average author sacrificing his life to write an all-ages novel.
The worst thing about porn addiction is that there are no physical dealers or substances involved. As long as your body is intact, all you need to become addicted is a screen and enough privacy, two things that are almost always available right before you go to sleep. And even without a screen, you can still use your imagination. Getting past that means finding other things in life to do that are more satisfying.
