How it's done: Stand facing your partner with your left foot turned out, perpendicular to your body, and your right foot forward. His legs should be slightly bent, spaced three feet apart. With your arms on his shoulders and his arms around your lower back, slowly pull your right leg up and prop your right foot on his left shoulder. Allow him to penetrate you. Then, ease into the vertical split by sliding your calf as far up his left shoulder as you comfortably can.

Why you'll love it: Most men are so inflexible, they think a knee bend is an Olympic feat, so he'll worship you as a sex goddess.
