Young Kissing Girls

In modern Western culture, kissing is most commonly an expression of affection. Between people of close acquaintance, a reciprocal kiss often is offered as a greeting or farewell. This kind of kiss is typically made by brief contact of puckered lips to the skin of the cheek or no contact at all, and merely performed in the air near the cheek with the cheeks touching. People may kiss children on the forehead to comfort them or the cheek to show affection, and vice versa.
As an expression of romantic affection or sexual desire in Western culture, kissing involves two people pressing their lips together with an intensity of sexual feeling. A couple may open their mouths, suck on each other's lips or move their tongues into each other's mouths (French kiss).
In Slavic cultures until recent times, kissing between two men on the lips as a greeting or a farewell was not uncommon and considered sexual. Symbolic kissing is frequent in Western cultures. A kiss can be "blown" to another by kissing the fingertips and then blowing the fingertips, pointing them in the direction of the recipient. This is used to convey affection, usually when parting or when the partners are physically distant but can view each other. Blown kisses are also used when a person wishes to convey affection to a large crowd or audience. The term flying kiss is used in India to describe a blown kiss. In written correspondence a kiss has been represented by the letter 'X' since at least 1763. A stage or screen kiss may be performed by actually kissing, or faked by using the thumbs as a barrier for the lips and turning so the audience is unable to watch the act.
In some Western cultures it is considered good luck to kiss someone on Christmas or on New Year's Eve, especially beneath a sprig of mistletoe.
