No one is suggesting that all porn actors are forced into it but there is a strong correlation between women who've suffered trauma and women who go into porn. Yes, there are sites like only fans where women are trying to make money. Most are making very little or feel that to make more they have to push their own boundaries. They also have to give 20% of their earnings to only fans which makes only fans pretty much pimps.
Or going back to porn movies/shorts. The most popular genre is Gonzo which pushes boundaries to their limits. Spitting, choking, "dry" anal, all holes filled, degradation as central to the whole thing. Women can say what they're not prepared to do then midway through a shoot be pushed hard to do more and if they don't they don't get paid. Pain, tearing, injuries. None of it is pretty. The women are harmed and in a different way so are the men who watch. On the one hand it's not real, on the other, for those being pounded and hurt it's all too real. One of the most popular sub genres within Gonzo? Barely legal.
None of this is okay. Real people are hurt. Real people whose idea of what they were entering into was delusional, which is not to blame them. They thought they'd have agency. Unless they're big stars they have little or no agency and as stars wane they're pushed/forced into more extreme scenarios.
And, of course, some women are forced. Trafficking is rife both in movies and only fans. And porn culture seeps out into wider culture. It affects all of us and it damages relationships. It creates expectations that are abhorrent to many of us. Ten, twenty years ago something like choking was a niche kink in the BDSM community, now it's been normalised. It's a disease that's spreading and causing real damage.
