After being "created" by a dog, Doggy Poo meets various living and inanimate things. No one wants to be his friend, and Doggy Poo becomes sad because he believes he is worthless and has no purpose. Eventually, a plant grows out of the ground and tells Doggy Poo that she needs him so she can grow into a flower. Doggy Poo discovers his life purpose and he becomes absorbed by the flower. After being absorbed by the flower, Doggy Poo lives "a happy life".
In ancient Rome, this practice was known as coitus more ferarum, Latin for "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.
The posture adopted by the receiving partner resembles 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. During vaginal penetration from behind, the penis may penetrate deeper into the vagina, reaching preferential contact with the posterior wall of the vagina and probably reaching 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 can reach the anterior fornix.
The active partner may also massage or stimulate the receiving partner's erogenous zones, such as the genitals, nipples, 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. The doggy position may be erotic or sexually provocative for participants.
Confirming its popularity, in 2015 a poll of 2,157 British men and women found that regionally, doggy style was favored by the Welsh.
Doggy style sex is a less physically demanding sex position and may be a preferred sex position if either partner has back issues or some other medical conditions.
Doggy style sex has advantages and disadvantages. In a doggy style position, a woman may feel exceptionally vulnerable, which some women find arousing in itself; while others consider doggy style sex unromantic. For some women, doggy style sex offers stimulation of an area that may be termed "the G-spot". However, this position may offer only minimal stimulation of the clitoris, so some women may require manual stimulation to achieve orgasm. Some men may, however, be able to stimulate the clitoris simultaneously with the penis and the scrotum respectively during doggy style sex.
The position is considered by some to be less intimate because eye contact and kissing are more difficult. According to the book Sexual Pleasure by Barbara Keesling, many established couples find doggy style sex relationship-affirming, as it requires and implies a level of trust and a surrender of control by the receiving to the active partner.
