STEP ONE

THE LURE

He's a sensitive songwriter with a guitar, that hair and real brains. ("I think I've always been verbose," he's said.) A Katy Perry pal says the pop star finds him to be "magnetic."

STEP TWO

HOOK, LINE AND SINKER

Once he's caught a woman, expect dinner dates, concerts and romantic getaways. He's said he has "the best of intentions."

STEP THREE

CATCH AND RELEASE

Mayer's romances are often on-and-off (see: Simpson; Aniston). One reason? "I'm too freaked out to meet anybody else," he's said.

STEP FOUR

CUTTING BAIT

When it's really over, some women are left floundering. Post-split, Simpson told PEOPLE, "I had to regain self-esteem and self-value."

STEP FIVE

FISHY BEHAVIOR

He can't help but kiss and tell: holding an impromptu sidewalk press conference after his first split from Aniston; calling Simpson "sexual napalm."

STEP SIX

GUTTED!

At least one ex seems to have gotten the last word. Swift's revenge song "Dear John" featured lyrics such as, "Don't you think I was too young to be messed with?" Mayer said he was "really humiliated."
