Dr. Sharon Mitchell co-founded the Adult Industry Medical Healthcare Foundation, also called AIM. For about 20 years she was a porn actress and director herself, and after opening her clinic, saw well over 1000 porn stars every month for STD testing, so it’s probably safe to say she knows a thing or two about porn stars. Dr. Mitchell says there are three types of women drawn to pornography: those who are desperate for money, those who are desperate for fame, and those who are addicted to sex.
