The leg wrap is a great variation of the timeless missionary position. It allows for deep penetration and plenty of clitoral stimulation.
Women have more control over the pace than in classic missionary: you can pull your partner towards you with your thighs. Your clitoris rubs against the base of his penis, adding extra stimulation. Also, if your partner is less well endowed, this will make him feel bigger.
One word of caution. If he’s heavy, the leg wrap could get uncomfortable. To help avoid this, he should be sure to take most of his weight on his arms.
