What a Butt Doctor and a Sexologist Want You To Know About Anal Oral

But with rimming, there are some safety precautions of note to explore first. Below, Alicia Sinclair, certified sex educator and CEO of b-Vibe, and Evan Goldstein, DO, anal surgeon and founder of Future Method, weigh in on what you should know before you dig in.

4 things a sexologist and anal surgeon want you to know about how to practice rimming safely.

1. Beware of bacteria

"Many folks have legitimate concerns about bacteria," says Sinclair. "The anus is where poop exits, so you have to be careful. Digestive bacteria and parasites such as E. coli and salmonella can be transferred from the butt to other body parts and pleasure tools during anal play." That means wiping thoroughly after bathroom use and cleaning your rectal region pre-anal play is so important.

2. Be mindful of precautions against STI transmission

According to Dr. Goldstein and Sinclair, one specific STI to always look out for is herpes. "It is super common and can definitely be transmitted both ways—anal to oral or oral to anal," says Dr. Goldstein "If there are any ulcerations that are present on either orifice, you should limit sexual activity until it’s been evaluated and/or fully healed."

Other concerns include but are not limited to chlamydia, gonorrhea, and HPV. If you're not up to date with your annual STI check and you're diving in with someone new, then Sinclair recommends that you use protection like you would (or should) with any other sex play. (And, consider getting an STI screening and asking your partner to do the same.) "A dental dam is your best option," she says.

3. You don't want to play in too many holes

Cross-contamination, it's a real thing! "It's important to keep that in mind to avoid infection by being careful not to ‘double-dip'—meaning that you shouldn't participate in any back-and-forth use of your sex toys, tongue, fingers, or penis," says Sinclair. "This also applies to ass-to-mouth action. Stick to butt stuff or vagina stuff, and don't cross over."

4. And don't forget to brush your teeth

When we talk about oral, we don't want to forget oral hygiene. "Studies have shown that rinsing with original-strength Listerine can help reduce the risk of transmitting certain types STDs," says Dr. Goldstein. "Prophylactic antibiotics or anti-fungals may be warranted if someone is experiencing recurrent infections, about two and three times a year."
