El sexo anal es una práctica sexual consistente en la introducción del pene (o de un juguete sexual en el caso de la masturbación anal) en el ano y el recto de la pareja. Otros términos sinónimos son «sodomía», «coito anal» y «pedicación». Además de en los seres humanos, se conoce la existencia de esta práctica entre primates y cánidos. Muchas personas encuentran placentero el sexo anal, y algunas pueden alcanzar el orgasmo mediante la estimulación a través del ano del punto G y del clítoris en las mujeres, así como mediante la estimulación de la próstata en los hombres. Sin embargo, muchas personas lo consideran doloroso, en ocasiones de forma extrema, lo que en algunos casos puede ser de origen psicosomático. Es posible también que una mujer penetre analmente a un hombre o a otra mujer por medio de una prótesis, que comúnmente va sujeta a su pubis por medio de un arnés. Esta variante del sexo anal recibe el nombre de pegging. En un enfoque ampliado la sexualidad anal abarca diversas formas de estimulación, desde la masturbación anal con los dedos al sexo oral-anal, conocido también como Anilingus.[cita requerida]

Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include fingering, the use of sex toys for anal penetration, oral sex performed on the anus (anilingus), and pegging. Though the term anal sex most commonly means penile-anal penetration, sources sometimes use the term anal intercourse to refer exclusively to penile-anal penetration, and anal sex to refer to any form of anal sexual activity, especially between pairings as opposed to anal masturbation. While anal sex is commonly associated with male homosexuality, research shows that not all gay males engage in anal sex and that it is not uncommon in heterosexual relationships. Types of anal sex can also be a part of lesbian sexual practices. People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved through anal penetration – by indirect stimulation of the prostate in men, indirect stimulation of the clitoris or an area of the vagina associated with the G-spot in women, and other sensory nerves (especially the pudendal nerve). However, people may also find anal sex painful, sometimes extremely so, which may be primarily due to psychological factors in some cases. As with most forms of sexual activity, anal sex participants risk contracting sexually transmitted infections (STIs/STDs). Anal sex is considered a high-risk sexual practice because of the vulnerability of the anus and rectum. The anal and rectal tissues are delicate and do not provide natural lubrication, so they can easily tear and permit disease transmission, especially if lubricant is not used. Anal sex without protection of a condom is considered the riskiest form of sexual activity, and therefore health authorities such as the World Health Organization (WHO) recommend safe sex practices for anal sex. Strong views are often expressed about anal sex. It is controversial in various cultures, especially with regard to religious prohibitions. This is commonly due to prohibitions against anal sex among males or teachings about the procreative purpose of sexual activity. It may be regarded as taboo or unnatural, and is a criminal offense in some countries, punishable by corporal or capital punishment; by contrast, people also regard anal sex as a natural and valid form of sexual activity that may be as fulfilling as other desired sexual expressions. They may regard it as an enhancing element of their sex lives or as their primary form of sexual activity.
