In a preview of Stormy Daniels’s upcoming book Full Disclosure, the Guardian helps answer a question that no one wants to know, namely what Donald Trump’s johnson looks like.

The award-winning English daily newspaper posted a preview of the book this morning, focusing on Daniels’s relationship with the future president back when he was a reality-TV star and New York City celebrity.

Daniels—a porno star and director—claims to have slept with Trump after a celebrity golf tournament in 2006, when he was married to his third wife, Melania.

In the book, the Louisiana-born actress alleges, based on her time with him and friendship over the years, that Trump never had any desire to be president. She also charges that Trump not only wanted to get her on his TV show Celebrity Apprentice, but also offered to cheat to help her win.

The Guardian piece has Daniels painting Trump as “petulant and prone to tantrums” and has her contending that she was approached in a gym parking lot by a large man in 2011 and told not to divulge any stories about her relationship with the future leader of the free world. Trump has derided that story as a “total con job” in the past.

He has also denied the affair, but has confessed to personally reimbursing his lawyer, Michael Cohen, for hush money given to Daniels in the run-up to his presidential bid.

The most horrifying part of the Guardian piece comes when it excerpts what the woman born Stephanie Clifford has to say about her allegedly sleeping with Trump. She describes his dong as smaller than average but “not freakishly small”.

“He knows he has an unusual penis,” Daniels writes in Full Disclosure. “It has a huge mushroom head. Like a toadstool…”

The sex was, by her account, not exactly mindblowing.

“I lay there, annoyed that I was getting fucked by a guy with Yeti pubes and a dick like the mushroom character in Mario Kart...It may have been the least impressive sex I’d ever had, but clearly, he didn’t share that opinion.”

In the months and years that followed, Daniels is quoted as writing that she’d see Trump on television, not believing that he was making headway in the presidential race. And, more importantly, not believing she slept with him, writing, “‘I had sex with that’, I’d say to myself. Eech.”
