There’s also a dynamic where people quickly get bored with porn and start consuming increasingly extreme or fringe porn to get the same satisfaction which I think is new. To clarify, kinks aren’t new, but just like political extremism, the internet is much better at radicalizing people into them.
I’m not sure if it’s good or bad, and I’m somewhat libertarian on the issue if only out of resignation, but I think that online pornography is extremely new and unprecedented and may indeed be very detrimental to society.
Anecdote of one, but I use it not infrequently and still have a healthy and fun sexual relationship with my spouse. Managed to produce two children and participate positively in society too. I may be baised, but I think I'm at most 25% degenerate. That being said, maybe I'll try going without for a while and see whether it has any effect.
Is porn/sex work really being "normalized" in a historically contextual way? Outside of about the last seventy years (maybe less), prostitution and sex work were extremely common, and, compared with the modern era, basically not criminalized. I'm not aware of a body of research that demonstrates a causal relationship between the consumption of porn and any social ill. I'm also not sure if I feel like I'm in a position to decide if OnlyFans customers would be better off without that outlet.
