The ass is a nerve center for all kinds of pleasure.
Rimming is exploring the anus with the tongue or mouth, or running the tongue between the butt cheeks.
The slang for this is known as ‘tossing the salad’. It can be done lightly, teasingly and playfully, or be given as a deep tongue-fuck, holding the cheeks apart for better access. It doesn’t even have to involve bodily contact: Try spitting and blowing gently, it can lead to unimagined pleasure. The great thing about rimming is the dual-pleasure of it. You can lick ass to show your submission, how grateful you are to serve your master, but it’s also a way of softening up the person you’re about to screw. Regardless of how and why you do it, enjoy it.
Lick first, fuck second is a good general rule, as anal penetration can produce tiny wounds in the anal fissure. Licking and being licked before fucking is a great way of having safer sex, as it entails only a minor risk of passing on HIV. Washing around the anus with soap and water before rimming also reduces the risk of transmitting intestinal bacteria. Having said that, don’t let hygiene set your rules. Think about what’s important for you, what turns you on. Is a clean body the same thing as a body that smells of soap, or is the body’s natural smell what really turns you on?
