Watching porn is healthy and normal. Like any form of entertainment it can be abused, but there isn't a moral panic about binge watching Netflix or video gaming. Like anything, it's best in moderation.
I'd say pornography has been normalized over time, but I'm not convinced it's inoffensive.
I won't polarize it and say it's bad. It is what it is, but I don't know if it can be categorized as healthy either.
That actually means absolutely nothing lmao.
