MILWAUKEE (AP) -- An 18-year-old man is pleading not guilty after being accused of having unprotected sex with a woman without telling her he was HIV-positive.

Rick Allen Brown of Milwaukee faces a charge of second-degree reckless endangerment.

According to the criminal complaint, the woman says they had sex three times last year, but Brown denied it to investigators, saying he only kissed her on the cheek.

The woman says Brown's aunt recently told her Brown is HIV-positive. The woman later received a call from Brown, who allegedly admitted he learned 18 months ago he is HIV-positive.

A judge ordered that Brown stand trial after the accuser told her side of the story in court yesterday. Brown pleaded not guilty.
