Doggy Style

Doggy style or doggie style (also known as doggy position) is a modern term for a group of sex positions in which the receiving partner crouches on all fours (usually on hands and knees). In ancient Rome this practice was known as coitus more ferarum or "sexual intercourse in the manner of wild beasts".} The specific origin of the term "doggy style" is not known, but is presumably a reference to the initial position assumed by dogs when mating. It is described in the Kama Sutra as the "cow" position or "the congress of a cow" and is listed in The Perfumed Garden.

Engaging in lordosis behavior – a physical posture seen in many female mammals, often when they are ready for sex/mating, the primary characteristic of which is a ventral arching of the spine – is considered by some people to be erotic or sexually provocative. During actual sex play between humans in the doggy style position, the receiving partner is, according to The Joy of Sex, regarded as the passive or submissive partner.

In doggy style, the receiving partner is available for a variety of sex acts, with the active partner being able to perform anal or vaginal or penetration from behind, as well as oral sex or anilingus. The active partner is also able to massage or stimulate the receiving partner's erogenous zones, such as the genitals, nipples, or buttocks, or administer a playful spank to the buttocks, or introduce a sex toy, such as a dildo or vibrator, into the vagina or anus.

During sexual intercourse in the rear-entry position the penis is in preferential contact with the posterior wall of the vagina and probably reaches the posterior fornix, while in the missionary position, it is in preferential contact with the anterior wall of the vagina and the tip of the penis reaches the anterior fornix.
