The lateral coital position is a sex position described by Masters and Johnson in their Human Sexual Response. The position was preferred by 75% of their heterosexual respondents once they had tried it.
The authors recommended that couples practice the procedure "in a humorous vein" while clothed and without sexual intercourse until proficiency is reached because achieving the position requires several movements.
Moving into this position requires that the partners begin with Woman on top sexual position and then:
This position leaves the partners both fully supported by the bed (the man on his back, the woman on her right shoulder and torso) except for the woman's left leg which is resting on the man's right hip. The man is flat on his back, while the woman is rolled slightly to her right. Their bodies form an angle of roughly 30°, leaving the partners face to face with the woman's weight on her right shoulder. Pillows are used under both partner's heads, more pillows may be needed to support the woman's upper body.
According to Masters and Johnson, "when facility in lateral coital positioning has been obtained, there is no pinning of either the male or female partner. There is mutual freedom of pelvic movement in any direction, and there will be no cramping of muscles or necessity for tiring support of body weight. The lateral coital position provides both sexes flexibility for free sexual expression. This position particularly is effective for the woman, as she can move with full freedom to enjoy either slow or rapid pelvic thrusting, depending upon current levels of sexual tensions."
The position was recommended by them for all couples, and also particularly in cases of premature ejaculation due to reduced pressure on the man.
