NEW YORK — Anthony Weiner says he's not dropping out of the New York City mayoral race in light of newly revealed explicit online correspondence with a young woman.

Weiner admitted on Tuesday to exchanging racy photos and having X-rated chats with a woman he met online. He had resigned his House seat in June 2011 after acknowledging having sexual conversations with at least a half-dozen women.

The newly revealed correspondence was posted Monday by the gossip website The Dirty. The woman involved, who was not identified, told the website she was 22 when she began chatting with Weiner on the social networking site Formspring. She said their online relationship began in July 2012 and lasted for six months. She claimed Weiner used the alias "Carlos Danger" for their exchanges, but she knew she was talking to the former congressman.

She said Weiner promised to help her get a job at the political website Politico and suggested meeting in a Chicago condo for a tryst.

The exchanges posted on The Dirty consist of sexually explicit fantasizing about various sex acts. At one point, the man reported to be Weiner wrote, "I'm deeply flawed."

The woman claimed that she and Weiner exchanged nude photos of themselves and engaged in frequent phone sex. The Dirty ran a pixelated photo of what appears to be a man's genitals.

"This was a bad situation for me because I really admired him. Even post scandal, I thought he was misunderstood. Until I got to know him. I thought I loved him. Pretty pathetic," the woman was quoted as telling the website.

She said he later asked her to destroy the evidence of their chats. She insisted that she never had sex with Weiner or received any payment from him.

The woman claimed her relationship with Weiner "fizzled" in November 2012. She said she last heard from him this past April, when his intention to run for mayor was first revealed in a New York Times Magazine profile.

The married ex-congressman had predicted more texts and photos might come out. Since re-entering public life this spring, he has apologized repeatedly for his behavior. He also has been near the top of most mayoral polls since entering the race.

The allegation could severely test voters' willingness to forgive Weiner, who has said he spent the two years since the scandal trying to make things right with his wife and earn redemption. Three of his rivals for mayor immediately called on Weiner to drop out of the race.
