Melbourne, Feb 11 : John Mayer has apologized for his Playboy Interview, saying he has 'created a monster' after spilling details about sleeping with ex-girlfriend singer Jessica Simpson and referring to his penis as a 'white supremacist'.

The Grammy-winner posted a series of tweets as media and bloggers began to attack him, reports the Courier Mail.

He wrote on Twitter: "And while I'm using today for looking at myself under harsh light, I think it's time to stop trying to be so raw in interviews."

Mayer said of his relationship with Simpson in the March issue of Playboy: "Sexually it was crazy.

"It was like napalm, sexual napalm. Did you ever say, 'I want to quit my life and just f***ing snort you? If you charged me 10,000 dollars to f*** you, I would start selling all my s*** just to keep f***ing you.'"

When asked if black women throw themselves at him, Mayer replied: "I don't think I open myself to it. My d*** is sort of like a white supremacist. I've got a Benetton heart and a f***in' David Duke c***. I'm going to start dating separately from my d***."
