Lip kissing, known more technically asosculation (osculate, meaning to touch, from the Latin "osculum", meaning kiss[1]) is not universal. It is not common in the traditional cultures ofChina orJapan.[2] The lip kiss is said to have been invented by the people ofancient India, although the earliest Indian records (about 2000 B.C.) indicate that their prior custom was anose or " sniff " kiss.[3] By the time the famous Indian manual of sex and love, theKamasutra, was written in the fourth century, the lip kiss was well established. The practice of kissing with the lips spread westward toPersia,Syria,Greece,Italy, and eventually to the countries that make upNorthern Europe.[4] The kiss on the lips is a practice that can be found in the time ofpatriarchs (Bible).[5] InAncient Greece, the kiss on the mouth was used to express a concept of equality between people of the same rank.[6] In theMiddle Ages, thekiss of peace was recommended by the Catholic Church.[7] The kiss on the lips was also common among knights.[6]
The gesture has again become popular with young people, particularly inEngland.[8][9]
There are also taboos as to whom one can kiss in someMuslim-majority societies governed by religious law. In the Islamic Republic ofIran, a man who kisses or touches a woman who is not his wife or relative can be punished such as getting whipped up to 100 times or even go to jail.[10]
Research from May 2023 found texts from ancient people in Mesopotamia that indicates that kissing was a well-established practice 4500 years ago. According to Dr Troels Pank Arbøll, one of the authors of this study:
"In ancient Mesopotamia, which is the name for the early human cultures that existed between the Euphrates and Tigris rivers in present-day Iraq and Syria, people wrote in cuneiform script on clay tablets. Many thousands of these clay tablets have survived to this day, and they contain clear examples that kissing was considered a part of romantic intimacy in ancient times, just as kissing could be part of friendships and family members' relations."[11]
On-screen lip-kissing was not a regular occurrence inBollywood until the 1990s, although it has been present from the time of the inception of Bollywood.[12] This can appear contradictory since the culture of kissing is believed to have originated and spread from India.[13]

AFrench kiss, also known ascataglottism or atongue kiss, is an amorouskiss in which the participants'tongues extend to touch each other's lips or tongue. Akiss with the tongue stimulates the partner's lips, tongue and mouth, which are sensitive to the touch and induce sexual arousal. The sensation when two tongues touch—also known astongue touching—has been proven to stimulateendorphin release and reduce acutestress levels.[citation needed] Extended French kissing may be part ofmaking out. The term originated at the beginning of the 20th century, in America and Great Britain, as the French had acquired a reputation for more adventurous and passionate sex practices.
French kissing may be a mode for disease transmission, particularly if there are open wounds.

Within the natural world of other animals, there are numerous analogies to kissing, notes Crawley, such as "the billing of birds, the cataglottism of pigeons and the antennal play of some insects." Even among mammals such as the dog, cat and bear, similar behavior is noted.[17]: 114
