“I could be dead right now!” Olson, 29, told Inside Edition on Tuesday. “I could literally be dead right now because he did not tell me that!”
Earlier this week, Sheen revealed that he is HIV-positive and insisted that he told all of his past sexual partners about his status. However, Olson has since claimed that he did not tell her of his illness during her stint as one of his live-in Goddess girlfriends in 2011.
Sheen’s manager, Mark Burg, exclusively denied Olson’s claims to PEOPLE on Tuesday, saying Sheen had been tested and was not infected with the virus when he and Olson were together.
Still, the 29-year-old is adamant that she knew nothing of Sheen’s illness, noting that the two had sex “every single night.”
She said that when the two did use protection, they used lambskin condoms, which do not protect from sexually transmitted diseases. She added that sex with Sheen was like playing “Russian Roulette.”
“That’s the best way to put it. It was like putting a gun to my head and pulling the trigger each time,” she said.
Olson maintains that she is not HIV-positive but has slammed the 50-year-old actor for putting her life at risk. She said that even if she had contracted the disease, she would not have kept her status hidden.
“I would never do to anyone what Charlie did to me,” she said. “That is giving someone a possible death sentence. I would never do that to someone ever.”

As for why Sheen would allegedly conceal his diagnosis, Olson said, “I don’t think he cared! I know he didn’t care!”
“Charlie, you’re a terrible person. You’re a terrible person,” she added. “I will never forgive you.”
Unlike Olson, former girlfriend Natalie Kenly, who overlapped with Olson as one of his Goddesses, came to Sheen’s defense.
“He is not a monster,” Kenly, 29, told PEOPLE exclusively on the eve of Sheen’s bombshell interview with the Today Show‘s Matt Lauer.
“He has regard for human beings and cares about people. I do not see him knowingly putting women at risk.” (Kenly, who says she is HIV-negative, now lives a quiet life in the Midwest with her young daughter and long-term partner.)
