PORN star Stormy Daniels told a magazine six years ago that she had an affair with President Trump starting right after his wife gave birth to their son, Barron — adding that the business magnate was nothing special in the sack.

“[The sex] was textbook generic,” Daniels, whose real name is Stephanie Clifford, told InTouch magazine in 2011. It “was nothing crazy. It was one position, what you would expect someone his age to do.”

According to the New York Post, the interview — which is being published for the first time in the magazine’s January 29 edition — surfaced on Wednesday.

Daniels now denies the pair had any relationship, although the Wall Street Journal recently reported that was because she was paid a reported $130,000 in hush money in October 2016. Daniels also denies being paid.

But the Good Will Humping star had already spilled the dirty details to the magazine years ago, according to InTouch, which also confirmed the account with her friends and had her sit for a polygraph test, which it says she passed.

Daniels and Trump met at celebrity golf tournament in Nevada in 2006 — after Trump had married Melania and when their son Barron was three months old, she told the magazine.

Daniels posted a photo of herself smiling next to a beaming Trump on her MySpace page in mid-July 2006.

She agreed to go back to his hotel room, where she said she teased him about his hair and he evaded her questions about Melania.

“He goes, ‘Oh, don’t worry about her,’ ” she told the magazine.

Eventually, Trump made his move, she said.

“He was sitting on the bed, and he was like, ‘Come here.’ And I was like, ‘Ugh, here we go,’ and we started kissing,” Daniels said.

“I actually don’t even remember why I did it, but I do remember while we were having sex, I was like, ‘Please don’t try to pay me.’ And then I remember thinking, ‘But I bet if he did, it would be a lot,” she said, according to InTouch.

Afterwards, he asked her to sign a copy of her X-rated film 3 Wishes, Daniels said.

Trump then became “smitten” and started calling her every 10 days, promising to get her on The Apprentice and referring to her as “honeybunch,” she said.

She also recalls Trump comparing her to his daughter, Ivanka.

“He told me once that I was someone to be reckoned with, beautiful and smart just like his daughter,” Daniels said.

Despite the then-60-year-old Trump’s unremarkable performance between the sheets, the pair continued to meet up, including in his office at Trump Tower, his vodka release party in Hollywood in 2007, and then at the Miss USA pageant later that year, Daniels told the magazine.

“Whether you’re a fan of his or not, which I never really was, you gotta admit he’s pretty fascinating,” she said of their ongoing relationship. “We had really good banter.”

In July 2007, Trump invited her to his suite at the Beverly Hills Hotel, where he admitted that he couldn’t get her on his reality TV show.

“He just kept brushing my hair off my shoulder and kissing my neck. And he was like, ‘So, can you stay?’ and I was like, ‘No, I gotta go.’ I left, and he kept calling me less and less over the coming months,” she told the magazine, adding that he finally stopped phoning her in 2010.
