20 Fun Facts about Kissing
Kiss” is from the Old English cyssan from the proto-Germanic kussijanan or kuss, which is probably based on the sound kissing can make.e [7]

The most important muscle in kissing is the orbicularis oris, also known as the kissing muscle, which allows the lips to “pucker.” [2]
French kissing involves all 34 muscles in the face. A pucker kiss involves only two. [2]
The lips of both men and women resemble the lips of the vagina. [3]
The term “French kiss” came into the English language around 1923 as a slur on the French culture which was thought to be overly concerned with sex. In France, it’s called a tongue kiss or soul kiss because if done right, it feels as if two souls are merging. In fact, several ancient cultures thought that mouth-to-mouth kissing mingled two lovers’ souls. [9]
The Four Vedic Sanskrit texts (1500 B.C.) contain the first mention of a kiss in writing. [3]
The Romans created three categories of kissing: (1) Osculum , a kiss on the cheek, (2) Basium, a kiss on the lips, and (3) Savolium, a deep kiss. [8]
Passionate kissing burns 6.4 calories a minute. A Hershey’s kiss contains 26 calories, which takes five minutes of walking–or about four minutes of kissing–to burn off. [3]
It is possible for a woman to reach an orgasm through kissing. [3]
Mechanically speaking, kissing is almost identical to suckling. Some scholars speculate that the way a person kisses may reflect whether he or she was breastfed or bottle fed. [3]
Kissing is good for teeth. The anticipation of a kiss increases the flow of saliva to the mouth, giving the teeth a plaque-dispersing bath.
Scientists believe that kissing may be a way of exchanging body salts or sebum that form relationships with parents and lovers, just as it does some birds. During mating, some birds chew food, then kiss-feed it to a prospective mate. If a bird’s sebaceous glands are removed so there is no sebum, its mate flies off. [10]
The Kama (desire) Sutra (type of verse) lists over 30 types of kisses, such as “fighting of the tongue.”
