8 Things You Never Knew About Kissing

Updated: Jan. 04, 2019

The only thing more fun than kissing is taking a breather to share your insider knowledge of the art form.


The longest kiss ever

Over the course of three days in 2013, a Thai couple locked lips for 58 hours, 35 minutes, and 58 seconds, to be exact. Ekkachai Tiranarat and Laksana Tiranarat started kissing on February 12 in Pattaya, Thailand, and didn’t stop until Valentine’s Day. The smoochfest took place at an event hosted by Ripley’s Believe It or Not and was recorded by the Guinness World Records. The title was a prize in itself, but the two diamond rings they also walked away with were probably a welcome bonus. Here’s how kissing actually makes you stronger.


The longest on-screen kiss ever

Slightly less time-consuming was the record for longest movie kiss ever recorded, the 3-minute-and-24-second liplock between two ladies in the 2010 movie Elena Undone. They broke the record previously set in 1941 in the film You’re in the Army Now, which lasted 3 minutes and 6 seconds. “The actors’ lips were glued together, so some people felt it shouldn’t count,” said filmmaker Nicole Conn. By the looks of the kiss, it’s clear that there was no glue needed.


Where you get your kissing style

Some fun facts about kissing: Common statistics show that two-thirds of people tilt to the right when they kiss, but what’s really fascinating is that your kissing style is actually genetic. German researcher Onur Güntürkün spied on couples in public places like parks, beaches, and airports in three different countries until he was able to conclude that most of the 224 smoochers leaned right. His major conclusion: Chances are, you’re likely to lean to the right, since that’s the direction our heads tilt in the womb. Fortunately, while kissing, your right is the other person’s left, which is great news if you’re worried about going the same way and bonking heads.

Weird laws about kissing

Are police actually handing out citations in Iowa or Indiana to men with mustaches kissing women in public? Probably not. But that law is on the books in those states. So is the law against men in Colorado kissing a woman while she is sleeping or kissing her at all on a Sunday. And in Florida, kissing your wife’s breast is a no-no. Don’t miss the weird marriage laws you might be breaking right now.


Women have cleaner kisses

Here are some interesting facts about kissing: Women are more likely than their male counterparts to initiate an early morning kiss in bed, possibly because they floss more often, so they’re less worried about bad breath, according to this infographic from DentalPlans. Women also have men outnumbered when it comes to brushing their teeth twice a day, but the odds of a woman telling her partner whether he or she has bad breath are just about even regardless of gender. Women are also more forthcoming when it comes to telling their partner if they have something stuck in their teeth. Guess the guys are erring on the side of caution—or perhaps they just don’t notice?


Fear of kissing is real

Fear of kissing is a legitimate phobia known as philemaphobia (philema is the Greek word for kissing). It’s most common among young or inexperienced kissers, but even in people of all ages, it may not get better with time and experience without the help of a therapist. But here’s the thing: Those whose fears are tied to the 80 million bacteria exchanged during kissing should know that it actually helps boost your immune system to swap that bacteria with others—it’s good for your teeth, too.


Where the X in XO comes from

Who better to ask for facts about kissing than a man whose full-time job it is to track down trivia? David Jacobson of Trivworks says that the “X” in “XO” is the letter that stands for the kiss, and cites several theories as to why that is. “The prevailing theory for how this came to be so prevalent, particularly at the end of written correspondence, is that during Medieval times, many people didn’t know how to read or write,” he says. “Rather, when signing important documents, they would simply draw or imprint an ‘X,’ an abbreviation for the word ‘Christ,’ which they would then kiss, out of reverence.” Thus, over time, the “X” came to be associated with the act of kissing itself, which is why it is believed to still be used in this fashion today.

The origin of the French kiss

The French have always been notorious for being adventurous and passionate in all matters of love and its expression. At one time, the “French Kiss” was known as a “Florentine Kiss”; the theory is that both American and British men coming back from Europe after World War I were planting ones on their wives with so much newfound fervor—and, gasp, enthusiasm for using their tongues—that people assumed they must have picked up this new set of skills while stationed in France. Which, in all fairness, they probably did. We’re glad they got credit where it was due. Next, don’t miss these hilarious first kiss stories that will make you happy you’re not a teenager.
