"That girl, for me, is a drug," Mayer, 32, tells Playboy in an at-times jaw-dropping new interview. "And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me."
Though Simpson and Mayer's on-again, off-again romance ended in 2007, the memory of those steamy romps still haunts Mayer. "Sexually it was crazy," he says. "That's all I'll say. It was like napalm, sexual napalm."
Before becoming paired with the pop star, Mayer never have considered dating Simpson, he admits. But he now says he became hopelessly hooked.
"There are people in the world who have the power to change our values," Mayer says in his candid confessional. "Have you ever been with a girl who made you want to quit the rest of your life? Did you ever say, 'I want to quit my life and just … snort you? If you charged me $10,000 to [sleep with] you, I would start selling all my [stuff].' "
Mayer is more discreet about former paramour Jennifer Aniston. "I love Jen so much that I'm now thinking about how bad I would feel if she read this and was like, 'Why are you putting me in an article where you're talking about someone else? I don't want to be in your lineage of kiss-and-tells'," he says.
