Sex work is work. Decriminalise it, legislate it, create a sex workers employment category and taxation, require licensing and health checks, give copyright protections to content creators, to their images and likenesses.
To me porn is no more fantastical than acting is.
I’m guessing the same reason there are professional certifications for stage combat coordinators, stunt choreographers, and firearms instructors even for movies. If doing your job poorly could very likely result in harm to others on the job site, there should be some standards and practices that are explicit and measureable, and like the SAE, maybe a trade group who assists their members with certs and continuing education.
Handling sexual activity on a set can definitely result in harm if done poorly or negligently.
Provides safety and rigour for the environments in which people work and provides a professional standard which indicates a person is trained / experienced / aware of the “right” way to do things.
Like at the very least, sexual health management, consent, grievances, injuries, comprehension of working conditions, rights, copyright, prevention of sexual slavery etc.
I know it’s onerous but the core of this is the worker and their health right.
