Anilingus (Rimming)

Anilingus, commonly called rimming, is the use of the mouth, lips, and tongue to stimulate a partner's anus and the surrounding perianal region. It is a widespread consensual practice across sexual orientations and is classed as a normal variant of human sexual behaviour rather than a disorder or paraphilia. The act may stand alone, precede or follow other forms of contact, or form part of broader oral, manual, or whole-body intimacy. This article traces the term's documented lineage, how the practice is typically expressed, its psychology, prevalence, and the hygiene and consent considerations that attach to it.

Definition & scope

Oral-anal contact covers a spectrum from light external contact with the perianal skin to focused stimulation of the anal opening itself. It is distinct from anal penetration and from manual anal play, though it often accompanies them. In community and sex-education writing the giving and receiving roles are tracked separately, since they tend to be reported at different rates. The act carries no clinical label of its own: it is a behaviour, and only the verb-noun "anilingus" formalises it.

Examples

What the term covers. Light, external contact with the perianal skin; focused stimulation of the anal opening itself; the act standing alone, or arriving before, during or after other contact; and either partner giving, receiving, or exchanging it. It is reported across orientations and in both same-sex and mixed-sex encounters, and by people who otherwise describe their sex lives as entirely conventional, which is the detail most often missed about it.

What the term does not cover. Anal play is the wider umbrella and takes in manual, toy and penetrative stimulation that anilingus by definition excludes, as do pegging and fisting. Felching is a distinct and far rarer act involving semen. Enema play concerns fluid retention and release rather than oral contact. The confusion that matters most is with coprophilia: rimming is not a faecal interest, is not reported as one, and the hygiene practice that surrounds it is aimed precisely at keeping the two apart. An interest in body odour for its own sake is olfactophilia. The other two oral acts, fellatio and cunnilingus, differ from it in anatomy and in infection profile rather than in kind.

How the word is used. Anilingus is the Latinate clinical form and the one sexual-health literature uses; rimming, rim job and the newer eating ass are vernacular, and tossing the salad is dated American slang. None of them appears in DSM-5-TR or ICD-11, because the act is a behaviour rather than a condition and the manuals have nothing to say about it. The variant spelling analingus is common enough to be unremarkable, though anilingus preserves the Latin.

History & origins

Clinical & lexical lineage

Oral-anal contact is an ancient, cross-cultural element of human sexuality, depicted in historical erotic art and referenced in classical and early-modern works long before it carried a clinical label. Wolfgang Amadeus Mozart, for instance, set the theme in scatological humorous canons in the 1780s, as noted in Wikipedia's account of the term. The modern word anilingus is a Latinate construction built on the Latin anus and lingere ("to lick"), formed on the pattern of cunnilingus. It entered English through the 1899 F. J. Rebman translation of the tenth edition of Richard von Krafft-Ebing's Psychopathia Sexualis (originally 1886), the same foundational sexological catalogue that named so many other interests of the era. Pioneering sexologists who documented the full range of sexual practice, notably Havelock Ellis in Studies in the Psychology of Sex (1897–1928), helped move such acts from moral censure toward neutral, descriptive treatment.

• 1780s: Mozart sets the theme in comic canons, an early-modern cultural trace of the practice.
• 1886: Krafft-Ebing publishes Psychopathia Sexualis, the catalogue that would carry the term into English.
• 1899: Rebman's English translation of the tenth edition introduces anilingus to Anglophone sexology.
• 1897–1928: Ellis's multi-volume Studies normalises descriptive documentation of oral and anal-oriented acts.
• 1948–1953: The Kinsey Reports on male and female sexual behaviour establish the survey-based study of ordinary adult practice.
• 1970s: The colloquial rimming (evoking the circular motion of the tongue around the "ring" of the anus) and toss someone's salad enter English slang, the latter traced to a 1970s gay-slang glossary.

Cultural evolution

Across the twentieth century, large behavioural surveys in the Kinsey tradition and later researchers progressively established oral and anal-oriented acts as ordinary features of consensual adult life. Contemporary diagnostic manuals, the DSM-5-TR and ICD-11, do not treat anilingus as pathological in any form. In recent decades mainstream sex-positive writing, magazine "A–Z" guides, and frank media discussion have made the practice and its slang vocabulary widely visible.

In practice

Expression ranges from light, teasing contact to more focused stimulation, and it is frequently combined with manual or genital stimulation. It may be given, received, or exchanged, and appears in both heterosexual and same-sex encounters. Many couples treat it as one option within a wider repertoire rather than a defining act. Because it places the receiving partner in an exposed, receptive position, communication and comfort tend to matter as much as technique.

Psychology

Why do people enjoy it?

The appeal is usually attributed to the dense nerve supply of the perianal area, the heightened intimacy and trust the act requires, and the taboo-tinged novelty some people find arousing. Because it places one partner in a vulnerable, exposed position, it can carry strong relational meaning around closeness, surrender, and acceptance. As a common, non-distressing behaviour it sits well within the range of ordinary sexual fantasy mapped by researchers such as Joyal, Cossette & Lapierre (2015), who found that the large majority of sexual interests reported by adults are statistically typical rather than atypical.

Prevalence & culture

How common is rimming?

Anilingus is a familiar, relatively widespread activity that features prominently on mainstream lists of bedroom practices, such as Glamour's A–Z of kinks and fetishes. Concrete figures come from clinic-based behavioural research. In a cross-sectional survey of 709 heterosexual attendees at the Melbourne Sexual Health Centre, Phillips et al. (2021) recorded the following for the previous three months:

The study noted that men were more likely to perform rimming and women more likely to receive it. Large fantasy and desire surveys such as Lehmiller's Tell Me What You Want (2018) likewise situate oral and anal-oriented acts firmly within mainstream sexual interest. Community and media visibility is high, and the slang vocabulary circulates widely in everyday culture.

Safety, consent & law

The principal practical consideration is hygiene and infection control. Oral-anal contact can transmit gastrointestinal pathogens (including Shigella and other enteric bacteria and parasites) and viruses such as hepatitis A, so washing the area beforehand and using a barrier such as a dental dam reduces risk. Moving the mouth to the genitals immediately after anal contact can introduce E. coli into the urethra and should be avoided. Between consenting adults in private it is legal and carries no clinical concern. As with any act, the only ethical requirement is that it be freely welcome to both partners.
