Charlie Sheen My Ex is Extorting Me ... She Wanted Unprotected Sex

Charlie Sheen says ex-fiancee Brett Rossi not only knew he was HIV positive, but insisted on having unprotected sex because she wanted them to be "like a normal couple."

Sheen claims Rossi is an extortionist who tried to squeeze millions of dollars from him by threatening to disclose his medical condition.

Charlie gets personal in his response to Rossi's emotional distress lawsuit, claiming as a porn star she's had "hundreds, if not thousands of sexual partners," and has exposed herself to STD's every time the camera rolls. Sheen says it's ridiculous for her to claim she got freaked out by his condition.

Sheen says Rossi wanted to have unprotected sex, and claimed she was a nurse and was seeing doctors who gave her anti-HIV meds.

He also flatly denies he was ever physically abusive to Rossi. And, he scoffs at her claim that he allegedly forced her to have an abortion.
