Michael Bergman was jailed in lieu of $250,000 bail, the St. Louis Post-Dispatch reported.

Investigators say Bergman may have had sex with five people, both men and women, since learning he was HIV positive. They are trying to trace his partners.

Bergman allegedly told the woman he believed she was already infected with AIDS -- "I don't want to lose you, I love you and I figured we could be sick together."

If the woman turns out to be HIV positive, Bergman could face more serious charges. He was charged with recklessly risking another person being infected with HIV, which carries a prison term of 5 to 15 years.
