Because it's super healthy to only see sex through the lens of porn
This is what scares me the most from this thread.
Each year proper sex education for young people is getting rarer everywhere, and in so many places it's now just completely nonexistent.
Teenagers and young adults receiving sex education nearly 100% through porn is so damaging. It's creating generations of people just completely unequipped to navigate real-life intimacy.
In an environment barren of proper sex education, at least with popular art forms like movies, TV shows, etc., young people can somewhat see more diverse, realistic, and often much healthier depictions of sex and intimacy. It's so important.
Just to springboard off your post here, because my concern isn't that your point here is invalid, it absolutely is. But, in my experience (and you can even see it in this thread), the follow-up to this idea is almost always "and so if you want to see this kind of content, you should just watch porn" which tends to be beside the point. Not only because I'd argue that porn and sex/intimacy as portrayed in theatric art serve different functions, the people making this point tend to not acknowledge (in the moment, at least) that the porn industry can grapple with the same problems of exploitation. And so what comes of as a solution doesn't feel like a solution at all, but more like we're shuffling the problem off to a "lesser" class of worker that society won't feel so prone to protect.
I think the solution is multifaceted. We need more intimacy coordinators, and we need more transparent negotiations regarding roles and contracts, so actors desperate to make it and keep their rent paid for the year aren't, as you have pointed out, essentially cornered into filming environments that they might not otherwise be comfortable with if they had real bargaining power.
But also, we really need to evaluate the ways we subtly shame sex. Because just as we should protect actors who might be pressured into sex scenes, we should also empower actors who would willingly and enthusiastically create sexual and sex positive portrayals in film without feeling like their images would be irrevocably "tainted" for doing so. I think we all should evaluate the socially ingrained sense of cringe we experience at idea of portrayed sexuality that feels "awkward" or "overproduced" or "too sexy." We rob ourselves of healthy examinations of sex, what it can look like, and the role it can and does play in many of our lives; we also place the burden on porn to do something it was never really meant to do.
Removing the taboo from sex also removes a lot of the power to exploit it. But that's a larger social problem.
All of this!!
smh we are never getting the era of the erotic thriller back at this rate
And it's such a shame...
