How it's done: Lie on your side with your back to your partner. He kneels next to you on the bed facing in the direction of your head, and slides his knee nearest to you between your legs. Open your legs just enough to give him access to your vagina — the closer together they are, the more pleasing friction he'll feel on his penis.

Why you'll love it: This sideways sex is even better than from behind, because the angle allows him to stimulate many of your normally hard-to-hit hot spots.
