''The man-on-top position is the most common form of lovemaking of the human kind. In the so-called missionary position a woman lies on her back with her legs spread. Either the man or the woman can guide the penis into the vagina.
In a variation of this position a woman can wrap her legs around the man's hips or back, or draw her feet up towards her chest. A man can elevate one or both of her legs or allow her to put them up over his shoulders. Whenever her legs are raised upwards the penetration becomes very deep. Although most women do not protest the deep penetration this position enables, a man should be quite gentle in such a position and look after his partner's comfort''

''How to do it: Find a spot for her to sit on that's about one foot lower than your pelvis . (Think: hood of a car, the boss' desk...) Stand at the edge, lean her back, and let her feet rest on your shoulders. Hoist her butt up with your hands so that her back forms a straight line, her pelvis is tilted upward, and your crotches are shaking hands.''
