FetLife is a good counterexample I did not know yet. And I completely agree: there is nothing wrong with women willingly doing porn.

But looking at other freely available porn, I cannot agree that only some porn studios treat their actors like submissive cash cows doing literally anything to feed the dopamine rush of their viewers. Sure the actors are paid for it. Prostitutes also get paid and still nobody would claim they are enjoying their job. In the end, we all need money to survive.
