And while it is an experience for many firmly rooted in adolescence, the French is a kind of kiss we never really grow out of, that never loses its position as a signal of intimacy. Sure, we grow out of calling it by the term French kissing (that sounds increasingly silly the closer you are to 40), or by those other charming labels like 'tonsil tangling' and 'swapping spit'. No matter how forcefully the social air-kissing of adult life invades our space, there is still a style of kissing that is and will always be reserved exclusively for those we lust, no matter what it’s called.
