kissing

Kissing is a form of physical affection characterized by pressing one's lips against another person or object. It commonly involves contact with lips or mouth, but can also include kissing on the cheek, forehead, hands, or other surfaces. Kissing occurs in many personal relationships, including romantic partners, family members, and friends, and its meaning varies by context. It is often a voluntary, affectionate act shaped by cultural norms and personal boundaries.

Types and techniques include a light peck, a longer shared kiss, and the French kiss, which involves open mouths and tongue contact. Other forms include the Eskimo kiss (nose or cheeks rubbing), the forehead kiss, and the air kiss (near the cheek with a kiss sound). Cultural practices and rules regarding kissing differ widely; in some cultures public displays of affection are common, while in others they are restricted or discouraged.

Social and health aspects: Kissing can convey affection, attraction, or farewell, and can play a role in mate selection and bonding. It often releases hormones such as oxytocin, dopamine, and endorphins. However, kissing can transmit infections such as influenza or herpes, so consent, hygiene, and awareness of medical conditions are important.

Evolution and psychology: Some researchers view kissing as a mechanism to assess partner compatibility and genetic or immune system compatibility, though opinions vary. Anthropologists note great variability in kissing practices across cultures and historical periods.
