French kiss

In English informal speech, a French kiss, also known as a deep kiss, is an amorous kiss in which the participants' tongues extend to touch each other's lips or tongue. A "kiss with the tongue" stimulates the partner's lips, tongue and mouth, which are sensitive to the touch and induce physiological sexual arousal. The oral zone is one of the principal erogenous zones of the body. The implication is of a slow, passionate kiss which is considered intimate, romantic, erotic or sexual.

A French kiss is so-called because at the beginning of the 20th century, in the English-speaking world, the French had acquired a reputation for more adventurous and passionate sex practices. In France, it is referred to as un baiser amoureux ("a lover's kiss") or un baiser avec la langue ("a kiss with the tongue"), even if in past times it was also known as baiser Florentin ("Florentine kiss"). The Petit Robert 2014 French dictionary, released on May 30, 2013, added the French verb "se galocher" — slang for kissing with tongues — making it the first time a single word described the practice (except in Quebec, where the verb "frencher" means French kissing; Australia, where the term "pash" is used; the German verb "knutschen"; the Italian verb "limonare"; and the Hungarian verb "megcsókol/csókolózik").

French kissing carries moderate risk of HPV. The possibility of contracting HIV from French kissing is extremely low as transmission would require an open wound.The CDC considers transmission of Hepatitis B via French kissing to be an unlikely mode of infection. Occasionally syphilis can be passed through prolonged French kissing, but this usually requires contact with an active lesion. French kissing is an unlikely mode of transmission of infection by Hepatitis B or gonorrhea.

In 2016, 29-year-old English footballer Adam Johnson pleaded guilty to kissing a 15-year-old girl with tongue, for which he received a 4-month sentence (reduced from a starting point of 26 weeks) for sexual activity with a child, to run concurrently with a six-year sentence for other offences against the same child.
