Pete Wentz has dished the dirt his sex life with wife Ashlee Simpson in a candid interview on U.S radio.

The Fall Out Boy rocker left little to the imagination as he went into detail about the new parents' sordid after-hours activities.

Pete told Howard Stern, "We have such sexual chemistry.

"If we had been on this show last year, we'd probably be doing it in the green room right now."

The rocker also decided to reveal the intimate details of their first night together.

"It was at the Soho Grand Hotel in New York City, and I'm looking in the mirrors, thinking, 'Oh my God, you are sleeping with the girl of your dreams, and you can watch yourself!'" he said.

But Pete is worried that having little Bronx Mowgli may throw off their mojo: "Hopefully, the kid doesn't change it."

We think after an interview like that Pete may find himself going without for a while...
