A very gorgeous man, who makes very gorgeous music, but has a very raunchy sense of humor, that isn't really that humorous. John Mayer also likes women with large breasts.
Gorgeous man: Google Image search (John Mayer)
Gorgeous music: Listen to his latest, "Continuum"
Raunchy Humor: “I’m not worried about how small my penis is – I’m worried about how dark it is. I have a Dominican penis. My penis hit six home runs last year; my penis wears shoes without socks.”
Large breasted women(that he's either dated, or has been linked to) Jennifer Love Hewitt, Heidi Klum, Jessica Simpson
