Taking time to explore these unchartered grounds spices up your usual routine and may lead to an increase in sex drive!

Ears

Not just for listening to your partner talk dirty anymore, these bundles of nerve endings are ultra-sensitive to touch. Use your index finger and thumb to massage and caress the outer ears with gentle, rhythmic pressure. Use your lips and tongue to explore the area behind the ear, throwing in an occasional gentle nibble here and there. Don't be afraid to exhale deeply while you explore, as the sounds of breathing (and perhaps a few moans of pleasure) are a supersonic turn-on. Be careful not to accidentally give your partner a wet Willie during this aural pleasure, though: there's nothing guaranteed to bring your session to a grinding halt like one of these schoolyard antics.

Scalp

Ever noticed how much people like to twirl and touch and fondle with their follicles and hair? Surprisingly, it's not usually vanity at the root of such behavior. Rather, most do it because it feels great. Next time you're anxious for a sexcapade, surprise your lover with a salacious scalp massage. Run your fingers through their tresses as you kiss, or simply sit behind them and gently caress the scalp. To up the erotic ante, try taking a bubble bath together, washing their hair with plenty of whole-body rhythmic scalp massaging.

Perineum

This collection of nerve endings is usually an intimate bystander when sex is on the menu. Sandwiched between the vagina or scrotum and the anus, it usually goes unexplored. Pity, because this rarely touched sensitive area delivers unexpectedly delicious pleasure. Start with light touching to warm up the skin and then gradually increase the pressure as the state of arousal increases. Get saucy and slippery by adding some lubricant to the experience.

Inner Thighs

This area is as soft as it is sensitive to touch and tongue. Even though inner thighs are rarely exposed during your average day, there are plenty o' nerves in the area that are primed for sensation. Gently kiss, suck and stroke the inner thighs, but resist the urge to take a bite (ouchie). If both horizontal dancers approve, though, a very gently nibble might be the dangerous sensation that sends you both over the top.

Feet

While some people cringe at the thought of popping someone's sweaty toe in their mouth, giving the feet some proper attention is a fantabulous way to ease into sex. Start by giving your love a footbath to clean away all that toe jam. Then rub in some scented oil (edible, of course) while you massage the feet to relax them. Spend time caressing the soles, toes, arches and ankles. Finally, grab one of those little piggies in your mouth and suck all the way home.
