A sexual act in which a person orally stimulates his or her partner’s anus. Anilingus (sometimes spelled “analingus”) is commonly known as a “rimjob” or simply as “rimming.”

Anilingus has more health risks than other forms of oral sex due to the high concentration of harmful bacteria surrounding the human anus. Washing immediately prior to sex can limit these risks. Dental dams can make the act significantly safer; when using a dental dam, a personal lubricant can improve sensation for the receiving partner.
