In my opinion, porn has lost, I hope not forever, its main function: to create sexual arousal in viewers.
There is no longer the psychological part (which is the one that activates the excitement function), there is no longer even the part attributable to the natural condition of those who attend the show.
I don't think viewers can reasonably identify physically with the actors, unless, today, men and women are all super-fitted, super-tattooed and super-rude. I'm not blind, I see very well and I see that most of the living humans are "normal" people.
In sex, even the more fetish or extravagant one, I still see a good common sense, a certain education, I don't see spitting, violent penetrations or cunnillinguus that last two minutes and then off we go. Similarly, I see normal, longed female orgasms, muscle stiffening or leg retraction, toe movements and some liberating scream at the end. Instead, in porn, everything is exaggerated, unreal, to the point of being annoying. I no longer watch porn, if not some niche productions, together with the partner of the moment, but more and more rarely. Could certainly be more exciting amateur video productions, as they are more realistic, 😃
