John Mayer is a little late to the party, but he's finally reacting to Katy Perry's claim that he's her number one ranking sexual partner.

Mayer tells Rolling Stone, "I don't have a cool enough thought for you," which is such a John Mayer answer.

But really, it seems that Mayer has settled down in his own way lately. He tells the magazine, "I've hacked this game. I pay very little of the price of fame now. I get to play the music that moves me the most. I'm having the time of my life. I'm 39 - I remember 32. I don't wanna do it again."

As for Mayer's dating life, he's made it clear that has also slowed down. He told the New York Times in March that he has "not dated very many people in the past five or six years."

Mayer is just doing his thing... and doing it well.
