Anthony Weiner estimates that he had sexual online relationships with "six to 10" women while in Congress and no more than three after resigning, a revelation comes as a new poll shows his support dropping.

“I don’t believe I had any more than three," Weiner told reporters when asked how many women he sent explicit messages to after stepping down in 2011. As for the number of women he corresponded with inappropriately while in office, Weiner said “six to 10, I suppose -- but I can’t tell you absolutely what someone else is going to consider appropriate or not.”

The New York City mayoral candidate said he was continuing to work with professionals on his issues but that he does not consider his online dalliances an addiction.

The candidate spoke Thursday from a soup kitchen in Brooklyn, where he hoped to highlight his plan to create a “Non-Profit Czar" for the city.

This more detailed account of his history comes as the gossip Web site The Dirty continues to publish excerpts of Weiner's interactions with Sydney Leathers, a 23-year-old Indianan who says she engaged in an online relationship with the ex-congressman for six months in 2012.

"Anthony Weiner is responsible for his downfall," Leathers told "Inside Edition" on Thursday. "I feel sick about it. I'm disgusted by him. He is not who I thought he was."

It was Weiner who shifted their relationship from professional to sexual, she said. When he decided to run for mayor, Leathers told the show, Weiner asked her to erase all of their Facebook conversations.

She compared their relationship to the Netflix show "House of Cards," in which a dishonest congressman has an affair with a young female reporter.

Meanwhile, a Marist/NBC/WSJ poll finds Weiner tied for second place among both registered and likely Democratic voters. City Council President Christine Quinn is once again in the lead.

“Weiner has lost his lead and his negatives are at an all-time high," pollster Lee Miringoff said.
