Quantasia Sharpton is one of three fans who sued R&B singer Usher, alleging that sexual intercourse with the star exposed them to herpes.

Sharpton, 21, recalled her encounter with Usher during a press conference with attorney Lisa Bloom Monday at the New York Hilton Hotel in Manhattan.

"I feel that my rights were violated," Sharpton said during the press conference. "I’m speaking out today on behalf of myself and others, some of whom are positive and embarrassed to speak out publicly. I am doing this so he does not do this to anyone else."

She is the first person to come forward publicly after the alleged herpes exposure claim. Sharpton claimed Usher failed to disclose his herpes disease before the two engaged in sexual activity two years ago.

"We spoke for a while and then we engaged in sexual contact," she said. "He never warned me about any STDs, it was just after my 19th birthday. When I first heard he had herpes I couldn’t believe it. I would have never consented if I had known."

Sharpton claimed she met Usher during his concert in 2015. She attended the show for her 19th birthday and gained backstage access before the show. She claimed that’s when Usher’s security guard approached her, saying the R&B star wanted her number. Sharpton claimed she received a call from Usher that night, asking her about her location.

"About an hour later, he arrived. We spoke for a while, and then we engaged in sexual contact. He never warned me about any STDs," Sharpton said.

Sharpton birthed a child at 19-years-old, according to her statement. She also admitted she had tested negative for the herpes virus.

"I had a child a year ago, and I knew I was negative," Sharpton said.

The 21-year-old tested negative for herpes. Despite her status, she sued Usher because she said he should have informed her of his herpes disease prior to sexual activity.

"When I first heard reports that [Usher] had herpes, I couldn’t believe it," she explained. "I contacted Lisa Bloom to find out what my rights are, as a woman. Although I am negative, I was upset by the reports because I would have never consented if I would have known. I would not have taken a risk of getting an incurable disease; my health is very important to me."

Bloom, who is representing Black Chyna in her revenge-porn case against her ex, reality star Rob Kardashian — explained Usher's actions endangered the safety of her clients.

"If Mr. Raymond is in fact a carrier of the virus, as these reports state, my three clients allege that he violated their rights by failing to warn them before having sexual contact with them," Bloome said. "If Mr. Raymond is negative, by allowing this story to go unrebutted for weeks on end, he has caused many people to be concerned about their reproductive health."

Sharpton ad Bloom looked to filed the lawsuit in California. Bloom cited the state’s law requires a person to disclose if they have a sexually transmitted disease with a partner before intercourse.
