Ohhhhh man. You went snooping through your man's stuff and and found his well-worn porn collection. (That'll teach you!) Before you dip yourself in Purell, take a moment to peruse his stash -- it could be the window to his sexual soul.

"Everybody has a unique 'lovemap' which is basically an index of their turn-ons and turn-offs," says sex and relationships counselor Ian Kerner, PhD, author of "Passionista" and "He Comes Next." "Porn can provide clues to a guy's fantasies."

We asked Kerner to weigh in on what your guy's tastes say about him ... and how you can use that info to improve your lust life.

Schoolgirls et al
Fortunately, Kerner says that checking out barely legal ladies doesn't necessarily mean that he's a Chester Molester.

"Guys realize that these aren't actual schoolgirls, but actresses performing a taboo -- the 'naughty innocent,'" says Kerner.

You can make the most of that turn-on with some schoolgirl-lite ideas: Don a white-buttonup with a plaid mini, ask him to "teach" you what to do in bed, call him daddy and make him talk you into sex ("Are you sure I won't get suspended if we get caught?"). Or don your old cheerleading uniform, a la Maria Bello and Viggo Mortensen in "A History of Violence."
