NYC’s Department of Health is bending over backwards to warn the public about a whole new threat — “rim jobs.”

The city’s health agency issued graphic guidelines for safe sex practices during the coronavirus pandemic Saturday, and while many were quick to take jabs at the agency for labeling masturbation safer than sex with a partner, most missed the backdoor rim shot.

Yes, the city specifically called out rimming — or using the tongue on the anal rim of another person for sexual pleasure — as particularly dangerous in a jaw-dropping section of the public safety alert.

“Rimming (mouth on anus) might spread COVID-19. Virus in feces may enter your mouth,” the city warned in the section titled, “Take care during sex.”

Eagle-eyed Twitter users, naturally, had a field day with the bizarre bullet point, whipping it into the butt of jokes online.

“The NYC Health Department has a document about sex and coronavirus that includes a statement about rimming,” one person wrote. “‘Stay at least six feet from other people, and be sure not to lick anyone’s anus.'”

“Day 13 of quarantine: my parents read the NYC coronavirus sex guidelines and are now discussing rimming at the dinner table. Need evacuation ASAP,” one person wrote.

Others were shocked the Department of Health didn’t let this particular sex act fall through the cracks — and in fact added it right after the section on kissing.

“The nyc coronavirus sex advice goes from kissing straight to rimming a-s which just goes to show how badly nyc was begging for a plague,” another joked.

Some, however, were impressed that the city poo-pooed the sex act, commonly known as a “rim job,” which is popular with many same-sex partners.

“Important, inclusive, informational. I’m here for this,” one person said.

The Department of Health reiterated advice to observe social distancing to prevent the spread of coronavirus on Saturday, days before the Big Apple became the epicenter of the virus with more than 13,000 cases and as many as 125 deaths from COVID-19.

The agency urged city dwellers to remain 6 feet apart from one another, but the document also offered “some tips for how to enjoy sex and to avoid spreading COVID-19.”

“You are your safest sex partner,” the document read. “Masturbation will not spread COVID-19, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.”

The agency, however, didn’t knock bumping uglies with a virus-free partner or live-in mate.

“The next safest partner is someone you live with,” the document continued. “Having close contact — including sex — with a small circle of people helps prevent spreading COVID-19.”

The document also encouraged seeking out sex in virtual form, including advising sex workers to turn to the web.

“If you usually meet your sex partners online or make a living by having sex, consider taking a break from in-person dates,” the document added. “Video dates, sexting or chat rooms may be options for you.”

So for those looking for rim jobs, best to try a Google search.
