What Is a Rim Job? A Clear, Practical Guide to Rimming (Anilingus)

"Rimming" — also called a rim job, or "salad tossing" in older slang — gets searched a huge amount, and yet there's remarkably little straightforward information about it — most of what's out there is either clinical to the point of being unhelpful or crude to the point of being useless. Here's a clear, practical answer.

What Is Rimming?

Rimming — the clinical term is anilingus — is oral-anal stimulation: using the mouth and tongue on a partner's anus. It's one of the more common sexual practices that people are curious about but rarely discuss openly, which is part of why the search volume around terms like "rim job" is so high relative to how little good information actually exists.

How Common Is It, Actually?

More common than the silence around it would suggest, and it's practiced across a much wider range of people than the stereotype implies. A large survey of nearly 25,000 men who have sex with men, conducted through an online hookup platform, found that roughly a quarter reported performing anilingus during their most recent sexual encounter, and about the same share reported receiving it. Separately, a survey of over 800 lesbian and bisexual women found that 29% reported rimming occasionally and 10% reported doing it often. Reliable data on heterosexual couples is harder to come by simply because most national sex surveys don't ask about it directly — not because interest isn't there, but because the research hasn't caught up to the question.

Why People Enjoy It

The anus has a dense concentration of nerve endings, similar in sensitivity to other highly responsive parts of the body. The tongue offers a kind of soft, warm, varied sensation that's genuinely distinct from fingers or toys — for a lot of people, that specific texture and warmth is a large part of the appeal. There's also a psychological element that shows up a lot in anal play generally: the intimacy and vulnerability of the act itself is part of what people find arousing, independent of the physical sensation.

How It Fits Into Anal Play More Broadly

Rimming is one piece of a much bigger picture. If you're curious about the rest of it — plugs, training, beads, prostate play, and partnered play — our guide to anal play kinks covers the full landscape, and the complete anal toys guide covers materials, safety, and what to actually buy.

The Hygiene Question (The One Everyone Actually Wants Answered)

This is almost always the real question behind the search. A thorough shower beforehand — with particular attention to the area — is the standard and sufficient approach for most people. Some people also choose to use an anal douche beforehand for extra confidence, though this isn't strictly necessary if regular hygiene is already part of the routine. A simple wash is genuinely enough for most people, most of the time.

Safety: What You Actually Need to Know

This is the part that gets skipped in a lot of casual advice, and it shouldn't be:

STI risk is real and broader than most people assume. Rimming carries real transmission risk for a longer list of infections than people usually expect — hepatitis A, hepatitis B, hepatitis C, herpes, HPV, and bacterial infections like chlamydia and gonorrhea can all potentially transmit through oral-anal contact, along with certain intestinal parasites. HIV is not considered easily transmitted this way, which is worth knowing if that's a specific worry. None of this requires visible symptoms to be present in order to transmit — that's exactly why it's worth being informed rather than assuming risk would be obvious. This isn't meant to create fear, just accuracy: it's a sexual activity with real risk, the same as any other, and deserves the same informed approach.

Sequencing matters, not just hygiene. One detail that rarely gets mentioned: going directly from oral-anal contact to oral or genital contact without a pause can transfer bacteria like E. coli into the urethra, which can lead to a urinary tract infection. If rimming is part of a longer session, it's worth being deliberate about the order things happen in, not just how clean everything is beforehand.

Dental dams reduce risk significantly. A dental dam — a thin barrier placed over the anus during oral contact — meaningfully reduces transmission risk while still allowing for the sensation and intimacy of the act. If you don't have one, a cut-open condom or a sheet of plastic wrap can work as a substitute, though purpose-made dental dams are the more reliable option.

Talk about it beforehand, including testing status. Like any new sexual activity, a conversation about STI status and testing history belongs before the activity, not as an afterthought. The hepatitis A vaccine, if you haven't had it, is also worth asking a doctor about if this is a regular part of your sex life.

Communication and Comfort

This is a practice that benefits from clear enthusiasm on both sides — checking in about whether it's something both partners actually want to try, rather than assuming. Some people love it immediately; others need a slower introduction, or aren't interested at all, and any of those responses are completely normal.

The Bottom Line

Rimming — whatever you call it, rim job, anilingus, or the older slang of salad tossing — is a widely practiced, widely searched, and widely under-discussed sexual activity. The survey data confirms it's a real and common part of many people's sex lives, well beyond the stereotypes attached to it. The essentials are straightforward: good hygiene beforehand, mindful sequencing during, a real conversation about safety and STI risk, and a dental dam if you want to significantly reduce that risk while keeping the intimacy of the act. None of it requires anxiety — just the same informed approach you'd bring to anything else.
