Sex positions are positions which people may adopt during or for the purpose of sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves the sexual penetration of the body of one person by another, or the stimulation of the sex organ of one by another, a sex position may not necessarily involve penetration or direct stimulation. Three categories of intercourse are commonly practiced: vaginal intercourse, involving vaginal penetration by the penis; oral intercourse, involving oral caress of the penis or vagina with a partner's mouth; and anal intercourse, involving insertion of the male's penis into a partner's anus. Sex acts may involve the use of fingers or hands or mutual masturbation such as grasping the man's penis or testicles and rubbing them around. There are numerous sex positions which the participants may adopt in any of these types of sexual intercourse or acts, creating an almost limitless number of sex positions. This list is based on Alfred Kinsey six primary positions as categories. Other forms of genital stimulation include (solo or mutual) masturbation, which may involve penetration by the use of fingers or hands, or by a device (sex toy) such as a dildo or vibrator.
These positions involve the insertion of a penis or other phallus (such as a strap-on dildo) into a vagina or anus.
Missionary, the most commonly used sex position.
Penetrating partner on top with front entry
The basic sex position is generally called the missionary position. In this position, the participants face each other. The receiving partner lies on his/her back with legs apart, while the penetrating partner lies on top. This position and the following variations are primarily used for vaginal intercourse, although some can also be used for anal sex. • The penetrating partner stands in front of the receiving partner, whose legs dangle over the edge of a bed or some other platform like a table. With the receiving partner's legs lifted towards the ceiling and resting against the penetrating partner, this is sometimes called the butterfly position. This can also be done as a kneeling position.
Anal missionary between two males
• The receiving partner lies on his/her back. The penetrating partner stands and lifts the receiving partner's pelvis for penetration. A variant is for the receiving partner to rest his or her legs on the penetrating partner's shoulders. • The receiving partner lies on his/her back, legs pulled up straight and knees near to the head. The penetrating partner holds the receiving partner's legs and penetrates from above. • Similarly to the previous position, but the receiving partner's legs need not be straight and the penetrating partner wraps his or her arms around the receiving partner to push the legs as close as possible to the chest. Called the stopperage in Burton's translation of The Perfumed Garden. • The coital alignment technique, a position where a woman is penetrated vaginally: the penetrating partner enters vaginally in the missionary position and moves slightly forward so that the base of the phallus rubs the clitoris. • The receiving partner crosses his/her feet behind his/her head (or at least puts his/her feet next to his/her ears), while lying on his/her back. The penetrating partner then holds the receiving partner tightly around each instep or ankle and lies on the receiving partner full-length. A variation is to have the receiving partner cross his/her ankles on his/her stomach, knees to shoulders, and then have the penetrating partner lie on the receiving partner's crossed ankles with his/her full weight. Called the Viennese oyster by The Joy of Sex.
