10 Things You Didn't Know About Kissing That You Should

What’s better than a good makeout session with a hot girl? Not much – not even boning. According to science (like all of science, the whole systematic enterprise), kissing is more important to a relationship than actual sex, so start changing your way of thinking.
In honor of National Kissing Day, we’re giving you the top ten facts about making out that you need to know. Get your chapstick ready and start doing your mouth exercises – it’s going to be a long night (hopefully, for you).

A Good Makeout Session Boosts Happy Hormones

You know that feeling you get after you finally drag your lazy ass to the gym? Yeah – it’s like that, but better. Endorphins kick in as soon as you pucker up and levels of the stress hormone cortisol lower significantly. According to Laura Berman, assistant clinical professor of ob-gyn and psychiatry at the Feinberg School of Medicine at Northwestern University in Chicago, “When you kiss, your brain releases this chemical that leaves you feeling connected and bonded to your mate.”

French Kissing Builds Your Immune System

According to a Dutch study published earlier this year, when french kissing for ten seconds, 80 million germs are transferred from one person’s mouth to another. While that’s totally f*cking gross, it’s actually pretty beneficial. By exposing your body to that amount of germs, it’s also building up your immunity to that bacteria. A 2010 study published in the journal Medical Hypotheses suggested that frequent makeouts between couples could help protect their babies from being infected in utero with cytomegalovirus, which can cause birth defects such as infant blindness.

Couples Who Kiss More Have Better Relationships

According to a 2011 study from the Kinsey Institute, both men and women reported being more sexually satisfied when their relationship consisted of kissing on a frequent basis. So in theory, some things are better than sex.

Women Value Kissing More Than Men

It’s a fact – so trust it. And work on your skills.

The Longest Kiss in History Was 58 Hours

Actually 58 hours, 35 minutes and 58 seconds, to be exact, and it was achieved by Ekkachai Tiranarat and Laksana Tiranarat. The couple is from Thailand, and made their mark in 2013 after entering an annual kissing competition. A cash prize, two diamond rings, and a Guinness World Record was given to them.

Kissing is Like a Taste and Smell Test

Researchers discovered that a scent believed to be the person’s DNA is picked up when kissing. Weird. Researchers also say that women are most attracted to the scent of a man whose genetic code is most different from their own, so maybe check that out? When you get a second?

Lips Are Super Sensitive

Like even more than your genitals, which is saying something. To put it in perspective, lips are 100 times more sensitive than the tips of the fingers, so act wisely.

Kissing is Good For Your Teeth

According to research, the anticipation of a kiss increases the flow of saliva, which in turn protects your teeth from plaque. This is not a reason to forego brushing, just saying.

Girls Start Kissing at a Younger Age

A nationwide study found that girls tend to have their first kiss around 14, while boys are on the slower side of the spectrum with the age range 16-18.

Kissing Came From Rats

Kazushige Touhara and colleagues at the University of Tokyo strongly believe that kissing traces back to an ancient rat called Eomaia scansoria, which used to “kiss” its mates by rubbing its nose against the other. This apparently sampled pheromones (hormones found in your sweat and other bodily fluids) and signaled sexual desire. Upsetting, but that’s life.
