Discover your hidden hot spots: your entire bod has erogenous-zone potential. Give your guy these tricks for finding your secret turn-on points and send him on a seek-and-enjoy mission. (Lust Lessons).

* If you've ever felt a sudden, sexy tingle between your legs when a guy stroked your back, touched your knee, or grabbed your waist, you already know the surprising way a random body part can become erotic. So why not capitalize on this idea? There are dozens of seemingly innocent places on your bod that can trigger an intense turn-on if touched the right way.

"The traditional erogenous zones make up a mere 5 to 10 percent of the whole body," says Gordon Inkeles, author of Sensual Massage for Couples, "But a little experimenting will reveal that you can register sexual arousal just about anywhere." Every sexy sensation you uncover will increase your overall ecstasy, so make up your mind to reach your pleasure pinnacle. Simply recruit a guy to be your personal explorer and have him try the following passion point-finding tricks.

Some of the most underrated erogenous zones on your body lie in territories you would normally consider too ticklish to touch. "But any body part that is ticklish can also be highly erotic because it's so sensitive," says Dennis Sugrue, Ph.D., coauthor of Sex Matters for Women. For a caress that won't result in a giggle jag, tell your guy to start by using his tongue. "He should lick the insides of your elbows, wrists, and knees with a flat, broad tongue and then blow on it to evaporate the moisture," says Sugrue. "This will create a contrast of warm and cold that's sexual, not ticklish."

Once he has fully explored the insides of your joints, ask your lucky lover to break out some massage oil and experiment with your hands. "Massage oil will blunt the ticklish effect," says Inkeles. After rubbing your palms with his thumbs, he should insert a lubricated finger between your digits, twisting the finger slowly while pulling it out. Another ticklish spot that typically gets ignored is the underarm--the musky smell is scientifically proven to be arousing. Says Graham Masterton, author of Wild Sex for New Lovers: "For a real treat, stash some moisturizer in the fridge and have him massage it into your armpits with soft to firm circular strokes."

If you're not the ticklish type, instruct your man to focus on the parts of your body that hardly ever get handled. "The insides of my upper arms never see the light of day," says Elizabeth *, 27. "So when my boyfriend lightly caresses me there, it feels really special." Other attention-worthy areas: the insides of your upper thighs, the crease between your butt and legs, the skin behind your ear, and even your nose.
