Anthony Weiner didn’t just send his latest sexting partner a crotch shot selfie with his young son curled up next to him in bed — he boasted to the woman about using his child as a “chick magnet.”

The stray-at-home dad’s stunning admission followed his repeated gripes about a lack of action in his marital bed, at one point complaining he was only having sex once every two months, according to screenshots obtained by The Post.

Weiner told the woman he had dropped off the tyke “at grandpas after school,” but bellyached that the free baby-sitting “only bought me a couple of hours,” the screenshots show.

“Put him to work,” the buxom brunette suggested during their March 12, 2015, online chat.

Weiner, 51, then sent the 40-something divorcee a photo of his son sitting in a playground swing, smiling and holding a toy car in his hands.

“Already at work. Being a chick magnet,” he wrote.

“It’s like a puppy. Chicks love cute kids and puppies,” she wrote back.

The picture of Weiner’s son, Jordan — now 4 — was among at least nine images featuring the boy that he sent the woman.

The trove includes the outrageous crotch shot that finally prompted wife Huma Abedin, 41, to announce she was leaving the sext maniac on Monday, hours after it was exclusively published by The Post.

Others show the boy lounging barefoot in an easy chair while wearing a Batman T-shirt and sweatpants, wearing shorts and a pair of shades for a mirror selfie shot with his dad, and wrapped in a towel and sitting in his dad’s lap in front of a palm tree.

One, showing him barefoot and wearing a gray, hooded bathrobe while standing in a carpeted elevator lobby, prompted the woman to exclaim: “Adorable!”

Weiner sent that picture via Twitter direct message on Dec. 4, 2015, minutes after asking the woman if she was “getting laid nowadays?”

She responded by asking “was that an invitation??”

“God. In a New York minute,” replied Weiner, whose since-deleted avatar showed him wearing a Mets cap.

The disgraced ex-pol’s claim about using his son as a “chick magnet” came after he repeatedly bemoaned his dry spell in the sack.

By then, he had forced Abedin to endure two sexting scandals, the first of which he tried to weasel out of by claiming to be a hacking victim before he came clean and quit his congressional seat in 2011.

Then, in 2013, Abedin publicly embraced Weiner as he mounted a comeback campaign for mayor — only to be humiliated again when her hubby was revealed to have kept on secretly sexting under the pseudonym “Carlos Danger.”

In a Feb. 7, 2015, chat with his latest online fling, Weiner whined that he hadn’t slept well and was “horny as f- -k,” spurring the woman to inquire why he wasn’t sleeping with Abedin.

“So you’re married and never w your wife?” she asked.

“We occupy the same space from time to time. Actually been very civil nowadays,” he answered.

“That’s nice. It takes a woman a long time to forgive if ever,” the sext partner wrote.

About two weeks later, Weiner declared: “I’m cranky, horny and generally ready for change.”

“Amen!!!!” the woman replied.

At the very start of their online relationship, on Jan. 23, 2015, Weiner told the woman his marriage was “busted,” as revealed by The Post on Tuesday.

Two days later, both of them were complaining how sex-starved they were.

“So busted marriage = pent up frustration??” the woman wrote, adding two frown emojis.

The woman — who had previously told Weiner that her live-in boyfriend traveled for work and was only home about 10 days a month — also noted, “So does long distance relationships.”

“Yeah but 11 days a month is a lot of sex,” Weiner jealously noted.

“If you’re lucky,” she wrote back.

Weiner, apparently referring to himself, then texted: “One sex in 60 days?”

“Crash & burn,” the woman replied.

Turning the conversation back to the woman’s boyfriend, Weiner then asked, “I thought he was around every third day?”

“And he’s usually working. Works a lot!! I just have no answers,” she lamented.

Weiner declined to comment on his “chick magnet” text or his complaints about his loveless marriage.

But in an email to The Post on Sunday, he admitted his online relationship with the woman, saying they “have been friends for some time.”

Asked about their sexting relationship, the woman told The Post she thought Weiner was a “broken” man.

“I don’t think he’s a bad guy. Maybe he’s an unfulfilled person. He’s in an unhappy marriage,” she has said.

In addition to the sickening photo that showed his son lying next to him and his crotch bulge, the other was almost identical to the image that first exposed him to national ridicule, except his undies were white instead of gray.

He also lusted after the woman, writing “Holy f–kity f- -k” when she sent him a selfie that showed her in a cleavage-baring, red lace dress — and even admitted masturbating while thinking about her.

Weiner should have learned his lesson years ago:
