How it's done: Have your partner lean back on a sturdy, high-backed chair with pillows behind him. First, straddle his erect penis with your hands on his knees. Then, one leg at a time, lift your ankles and hands to support your weight and moving your behind back and forth.

Why you'll love it: This position is really intimate. Only your gyno has seen you this close. Your guy will be fantasizing about the view for weeks to come.
