How it's done: Lie on your side, one arm propping up your head or bent under your body for support. Keep one leg stretched out along the floor and extend the other straight up in the air perpendicular to your body. Your partner then straddles your grounded leg and enters you, holding your other leg up or letting it rest against his shoulder for leverage, whichever suits his style.

Why you'll love it: Unlike most sex positions, this gives you a great view of the action (a major turn-on). And your guy can penetrate you in up-and-down motions instead of regular back-and-forth thrusting. The different strokes will bring on ultrasensual new sensations.
