The anus has a relatively high concentration of nerve endings and can be an erogenous zone, which can make ♥♥♥♥ intercourse pleasurable if performed properly. The pudendal nerve that branches to supply the external ♥♥♥♥ sphincter also branches to the dorsal nerve of the ♥♥♥♥♥♥♥♥ and the dorsal nerve of the ♥♥♥♥♥.

Sigmund Freud's theory of psychosexual development, for example, described an ♥♥♥♥ stage, hypothesizing that toddlers derive pleasure from retaining and expelling feces. This is the source of the term "♥♥♥♥-retentive" and the derived informal term "♥♥♥♥".

In addition to nerve endings, pleasure from ♥♥♥♥ intercourse may be aided by the close proximity between the anus and the prostate for males, and ♥♥♥♥♥♥, clitoral legs and ♥♥♥♥ area for females. This is because of indirect stimulation of the prostate and ♥♥♥♥♥♥ or clitoral legs.For a male insertive partner, the tightness of the anus can be a source of pleasure via the tactile pressure on the ♥♥♥♥♥. Pleasure from the anus can also be achieved through ♥♥♥♥ masturbation, fingering, facesitting, anilingus, and other penetrative and non-penetrative acts. ♥♥♥♥ stretching or fisting is pleasurable for some, but it poses a more serious threat of damage due to the deliberate stretching of the ♥♥♥♥ and rectal tissues; its injuries include ♥♥♥♥ sphincter lacerations and rectal and sigmoid colon (rectosigmoid) perforation, which might result in death.Lubricant and condoms are widely regarded as a necessity while performing ♥♥♥♥ ♥♥♥ as well as a slow and cautious penetration.

♥♥♥♥ intercourse is sometimes referred to as sodomy or buggery, and is considered taboo in a number of legal systems. It has been, and in some jurisdictions continues to be, a crime carrying severe punishment.
