I'm kind of disappointed that porn is even a thing... I feel like if we weren't so scared of our bodies and sex, and if society didn't freak out over the nipples of 50% of the population (but not the other 50%) then porn wouldn't be the massive industry that it is.

I don't think that's the reason why porn exists. Porn has always existed. It's all about visual and auditory superstimuli. It's to the sex drive what high-fructose corn syrup is to hunger: a highly processed and somewhat unhealthy way to satisfy our urges. Neither is good for anybody in large doses.

There has never been and never will be a sextopia where everyone is satisfied. The reality of sex can be a pretty harsh place fraught with vast range of difficulties and problems. Porn and its use will always range from the harmless and fun to the pathological. But you're right in that the ubiquity of audiovisual material in our world warrants educating people and the youth in particular much better on the perils of too much porn use.
