Traditional porn involves sex with strangers. Your getting tested regularly for STDs. Your usually an actor being hire and payed. There are interviews, contracts. Usually there is a camera man, director, lighting, sound, makeup, extra. Your basically having sex in front of many people. And there multiple takes.
Most of MFC, your just by yourself. You have to do every thing. Your lighting, sound, makeup, camera man, model, extra. Your not being payed because you showed up; you got to hustle.
Porn there is usually a script, you don't have to be a social butterfly. MFC your talking to a ton of people constantly.
Some people do both. And there are couples who cam. And the occasional cam cross over. I don’t think there are the same protection for cam models that there are for traditional porn actors. Like mandatory, regular testing. (for people who are having sex with strangers)
