A French kiss

A French kiss is a kiss in which one or both participants' tongues touch the partner's lips or tongue, usually entering their mouth. A French kiss is a slow, passionate kiss which is usually considered intimate, romantic, erotic or sexual.

A "kiss with the tongue" stimulates the partner's lips, tongue and mouth, which are sensitive to the touch. The practice is often considered a source of pleasure. The oral zone is one of the principal erogenous zones of the body.

In early human societies, mothers weaned their children by chewing up their food and then passing it into the infantile mouth by lip-to-lip contact- which involved a considerable amount of tonguing and mutual mouth pressure. Our species practiced this behavior for over a million years, and adult tongue kissing today is considered a relic gesture stemming from these origins.

Etymology

A French kiss is so-called because at the beginning of the 20th century the French had a reputation for more adventurous and passionate sex practices. In France, it is referred to as baiser amoureux ("lover's kiss") or baiser avec la langue ("kiss with the tongue"), even if in past times it was also known as baiser florentin ("Florentine kiss").

Biology

According to the biologist Thierry Lodé tongue kisses, including the exchange of saliva, allows lovers to explore the immune system in order to avoid other people who have too much genetic relatedness. Indeed, from an evolutionary point of view, the sexual partner should be different to be attractive and to provide the genetic diversity that promote the health of the immune system progéniture. The Smell Identification salivary amended by the immune system, can trigger desire, love consent, and finally the sexual act itself.
