Analingus or rimming is simply using your mouth, tongue, lips and sometimes teeth to stimulate your partner's anus and (in the case of a male recipient) his testicles. As the anus has so many sensitive nerve-endings, it can be incredibly pleasurable for both men and women. Lots of couples enjoy rimming during foreplay, or as a sexy accompaniment to oral sex.
Rimming is sometimes referred to as 'playing the rusty trombone', which is when the person who is giving the oral attention also reaches around to the penis and makes rapid stroking movements up and down the shaft. The mouth-to-bottom coupled with arm actions resembles someone playing a brass instrument.
