Musician John Mayer is getting very frank about his past relationships with Jessica Simpson and Jennifer Aniston. In a latest interview with Playboy, the rocker compared Jessica to a drug and said he still loves Jen.

The on and off boyfriend of Jessica, Mayer said, “That girl, for me, is a drug. And drugs aren’t good for you if you do lots of them. Yeah, that girl is like crack cocaine to me. Sexually it was crazy. That’s all I’ll say.”

John told Playboy about his relation with Jessica that “It was like napalm, sexual napalm.”

The 32 year old musician told the magazine that he felt addicted to the Jessica.

The rocker said, “There are people in the world who have the power to change our values. Have you ever been with a girl who made you want to quit the rest of your life?” he continued. “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 shit just to keep f****** you.’”

Talking about his ex girlfriend Jennifer, Mayer said, “Yes, always. I’ll always be sorry that it didn’t last,” John said. “In some ways I wish I could be with her. But I can’t change the fact that I need to be 32.”

The rocker did not reveal whether his latest album, “Battle Studies,” is about Jen or not, but says he hopes his music will relate to everyone’s lives.

He told reporter, “I feel bad because people think ‘Heartbreak Warfare’ is about [Jen]. I want to go on record saying it’s not. That woman would never use heartbreak warfare. That woman was the most communicative, sweetest, kindest person. When people hear the record, I hope the songs make them think about their lives, not my life.”

He added, “We just have a regard for each other’s feelings that is pretty intense. It’s been a deep relationship, and it’s no longer taking place at all. Have you ever loved somebody, loved her completely, but had to end the relationship for life reasons?”
