Seventies pin-up Pam Grier and comedian Richard Pryor's doomed 18-month romance ended when he took issue with her requests for him to wear a condom during sex.
The actress' doctor told her that cocaine-user Pryor's sperm was harming her body - because it contained traces of the drug.
And he insisted she should demand protected sex.
Appearing on The Oprah Winfrey Show on Thursday (03Feb11) to promote her new memoirs, Foxy: My Life in Three Acts, the Foxy Brown star revealed, "There was an epidemic of a lot of people doing cocaine and it accumulated in the body and often in the prostrate gland and it would come out during your sexual activity, and inside a woman it could harm her.
"(My doctor) said, 'You'll have to ask your mate to wear protection...' It would protect me from getting the drug into my body... and so I had to tell Richard, 'You're gonna have to wear a raincoat', and he had an issue with that.
"I said, 'It's my life...' I chose me."
