Don´t know any of this by first hand, but this is what I have heard:
Desiree: went nuts. Heard she was in an asyllum.
Kay Parker: spiritual consultant, therapist and a writer (just wrote a book about her life, including her life as a porn actress)
Gloria Leonard: still conected with the industry. Once in a while apaers in movies as an extra or in a no-sex roll. Also produces some movies and writes articles on sex and the porno industry.
