The missionary position is a male-superior (man on top) coitus position in which the woman lies on her back an the partners face each other. Variations of the position allow different degrees of vaginal tightness, clitoral stimulation, depth of penetration, participation on the part of the woman, and likelihood and speed of orgasm. These variations may involve the woman resting her feet on the bed, lifting them up high into the air, or wrapping them around her partner; or placing one or more pillows under the woman's hips.
