Kissing in Western culture
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).
