Thanks for your question. Rimming is also known as anilingus, eating ass or eating out. During rimming, partner(s) use their tongue to suck, kiss, lick or orally stimulate the anus of the partner. It is important to remember pleasurable sexual experiences always involve consent.
While giving or receiving anilingus can be pleasurable, it can result in the transmission of some sexually transmitted infections like Hep A, Hep B, Herpes (HSV), Human Papillomavirus (HPV), syphilis and sometimes chlamydia and gonorrhea.
To reduce the risk of STI transmission, cover the anus with a sex dam or a cut condom. Sex dams usually come in various flavors (vanilla, banana, grape, strawberry, mint, etc). Adding lubes along with sex dams can add to the pleasure factor.
