Description

Anal sex (also called anal intercourse) is the sex act in which the penis is inserted into the anus of a sexual partner.[1][2] The term can also include other sexual acts involving the anus, including pegging, anilingus (anal–oral sex), fingering, and object insertion.[1][2]

Common misconception describes anal sex as practiced almost exclusively by gay men. This misconception is dispelled by researchers, who state that not all gay males engage in anal sex and that anal sex is not uncommon in heterosexual relationships.[1][2] Types of anal sex can also be performed as part of lesbian sexual practices.

Many people find anal sex pleasurable, and some may reach orgasm—through stimulation of the prostate in men, and clitoral and G-Spot leg stimulation in women.[3][4] However, many people find it painful as well, sometimes extremely so,[5][6] which may be psychosomatic in some cases.[6]

As with most forms of sexual interaction, individuals are at risk for contracting sexually transmitted diseases,[7][8] and therefore safe-sex practices are advised.[7] Anal sex is considered a high-risk sexual practice, and unprotected anal sex is the riskiest of all forms of sexual intercourse,[1] due to the vulnerability of the rectum and sphincter tissues.[1][2] It is also controversial in some religious traditions, often due to prohibitions against homosexual sex acts and/or to teachings about the procreative purpose of sex. However, as attitudes toward sexuality have changed in recent years, many religious groups, especially in Euroamerican Judaism and Christianity, have become more accepting of non-procreative sex.

The abundance of nerve endings in the anal region and rectum makes anal sex pleasurable for many men and women.[9] "The opening and closing of the anus is controlled by the internal and external sphincter muscles (the most important muscles when engaging in anal sex). The sphincter muscle is a sensitive membrane with many nerve endings and thus the source of pleasure or pain."[10]

In a male receiving partner, being penetrated can produce a pleasurable sensation due to the inserted penis rubbing or brushing against the prostate (also known as the "male G-Spot", "P-Spot" or "A-Spot") through the anal wall.[3][11] This can result in pleasurable sensations and can lead to an orgasm in some cases.[3] The prostate is located next to the rectum and is the larger, more developed[12] male homologue to the Skene's glands, which are believed to be connected to the female "G-Spot".[13]

The Skene's glands are sometimes referred to as the "female prostate";[14] they are located around the urethra and can be felt through the wall of the vagina. However, research shows most women achieve orgasm only through clitoral stimulation.[15][16][17][18][19][20] The clitoris surrounds the vagina somewhat like a horseshoe and has over 6,000 nerve fibers.[21] In addition to nerve endings present within the anus and rectum, a physiological explanation for why some women may find anal stimulation pleasurable is that the clitoris has "legs" which extend along the vaginal lips back to the anus.[22] The Grafenberg spot, or G-Spot — a small area behind the female pubic bone surrounding the urethra and accessible through the anterior wall of the vagina — is considered to have legs in relation to the clitoris[15][23] which may also be accessible through anal penetration. Stimulation of the clitoris, G-Spot, or both, during anal sex may help some women to enjoy the experience.[24]

In pornography, anal sex is often presented as routine and painless, but according to Go Ask Alice! and other researchers, anal sex occurs "much less frequently" than other sexual behaviors.[1][25] The increase of anal activity among heterosexuals has been linked to the increase in anal pornography,[1] and the association with dominance and taboo make anal sex appealing to people of all sexual orientations.[26] Moreover, an anus is usually tighter than a vagina, which can yield greater tactile pleasure for the man via his penis.[27]

While each person's sphincter muscles react to penetration differently, the anal sphincter in general has delicate tissue that can tear, and the rectal mucous membrane provides insufficient natural lubrication for sexual penetration. Researchers say adequate lubrication, relaxation, and communication between sexual partners are crucial to avoid pain or damage to the anus.[1][4][6][24][26][28][29] Ensuring that the anal area is clean and the bowel is empty (for both aesthetics and practicality) is also advised.[1]

 

Анален секс (анално проникване, анално сношение) е сексуална практика, при която пенисът на единия партньор се вкарва в ануса на другия, с цел получаване на сексуално удоволствие. Използването на различни секс играчки за стимулиране на ануса и ректума също се счита за анален секс.

Аналният секс може да достави удоволствие както на проникващия, така и на приемащия партньор, тъй като анусът притежава нервни окончания, подобни на тези по клитора и пениса. Смята се, че за жените аналният секс е приятен, тъй като по този начин се стимулира преградата между ректума и вагината, а също и Г-точката. Това доставя неповторимо удуволствие на жената, което е различно и не може да се усети по време на класическия секс. При мъжете отвъд ректалната преграда се намира простатната жлеза, чието дразнение при анален секс също е източник на удоволствие.

В някои култури аналният секс се разглежда като табу и е обявен за противозаконен от някои законодателства (виж Закон против содомията).

При практикуване на анален секс е необходимо особено внимание, търпение, както и употребата на лубриканти, тъй като, за разлика от вагината, анусът няма естествена лубрикация. В противен случай актът може да е болезнен за приемащия партньор, а в по-драстични случаи - да доведе и до наранявания.

Както и вагиналният секс, аналният секс без предпазни мерки създава опасност от заразяване с полово предавани болести. Освен опасността от зараза, съществува и чисто физиологична опасност от наранявания и разкъсвания. По тази причина, в ануса не бива да бъдат вкарвани предмети с ръбове и остри върхове, както и въобще предмети над 20 см, тъй като може да се увредят стените на дебелото черво.
