John Mayer Calls Jessica Simpson 'Sexual Napalm'

What does that even mean?

John Mayer is not shy about kissing and telling. The singer-guitarist has had carnal dealings with some of Hollywood's hottest stars, and after each one he usually spills the beans. Now it's Jessica Simpson's turn: in the latest issue of Playboy, Mayer calls her "crazy" in bed.

According to UsMagazine.com, which got a first look at Playboy's March issue, Mayer, 32, talks about a few of his high-profile relationships and says one in particular, Jessica Simpson, was like a dangerous drug.

"And drugs aren't good for you if you do lots of them," he says. "Yeah, that girl is like crack cocaine to me."

Mayer and Simpson dated from 2006 to 2007, and it seems the buxom blonde burned an indelible image of herself into his brain.

"Sexually it was crazy. That's all I'll say," says the "Your Body is a Wonderland" singer. "It was like napalm, sexual napalm. Did you ever say, 'I want to quit my life and just f-----’ snort you? If you charged me $10,000 to f--- you, I would start selling all my s--- just to keep f------ you.'"

Sexual napalm? Really? So, does that mean she's just good in bed, or does she actually strip the flesh off the bones of men?

As for his other much-publicized relationship with Jen Aniston, Mayer only had polite things to say about the actress. He calls her "the most communicative, sweetest, kindest person."

Mayer also tells Playboy about his shame over his reputation as a dirty-dog. "I hate being the heartbreaker. Hate it," he says. "If I date somebody and it doesn't work out, it's another nightmare for me."
