9.4% of men in an official Swedish study from 2017 said they have paid for sexual services (0.5% of women). It's a minority but still almost 1/10. I can only imagine that OnlyFans has normalized this behavior a lot since then.
There's also the narrative that people on these platforms are choosing to do this because they make a lot of money, and that it's less problematic than the rest of the porn industry somehow. I'm very sceptical about both of these notions.
That is what I meant, I understood you comment as "paying for OnlyFans" is human nature. I would dispute that as a general statement because I believe it is a very special demographic that does that.
I would understand human nature to mean that it affects every human, but sure, after that definition I guess it remains some form of constant at least.
