The Real Housewives of New York star, Sonja Morgan, flipped the interview tables on Cohen and things started out innocent enough.
"Today, my celebrity crush is Zac Efron," Cohen shared, "because there were just these really racy pictures of him that came out of him on the beach. He looks great and he's wearing these kind of panties a little bit, and it was a little bit, kind of, sexy."
But then things got spicier.
Morgan wanted to know if Cohen has ever slept with a woman, and the host said candidly, "No, not fully." But he admitted to experimenting.
After that, the sex talk continued. Cohen revealed the craziest place he's ever had sex is "under the stands at Hollywood High School."
And "don't be worried about me," Cohen said, regarding his sex life, since the last time he had sex was "Sunday morning." The interview took place on Tuesday.
But then Cohen dropped the real bombshell: "The most famous person I ever slept with, I guess, is Lance Bass."
Must have been years ago, though, since Bass just recently tied the knot with now-husband, Michael Turchin.
Check out the full interview below where Cohen shares all sorts of dirty details.
Cohen has been open about his past before.
He told E! News that he and his best friend, Anderson Cooper, met decades ago on a blind date.
"We were set up on a date," he explained. "Not many people know this, but the way Anderson and I met about 20 years ago is we were set up on a blind date. It didn't take. It just didn't work. We're meant to be best friends... we're meant to be good friends and not boyfriends."
