This is a great position for G-spot stimulation. The Wedge adds more tilt to her pelvis, thus adding more friction to the upper area of her vagina, where the G-spot is located. It’s also a wise use of the Wedge for a couple who differs in height. If he is a lot taller than she is he can use this position to bring her closer to his pelvis region. Try varying the position by having her legs under his arms and to the outside of his arms...
