Why do we kiss?
Nothing makes us weak at the knees quite like a passionate kiss; even seeing romantic embraces in films can make our stomachs do back-flips. So perhaps it's not surprising, given our fascination, that there's a whole science dedicated to the study of kissing (philematology). This is designed to discover why we do it, how it benefits us, and what it really means.
CNN Health reported that kissing provides sensory clues — including taste, sound, and smell that instinctively help the kisser decide if they want to carry on kissing the object of their affections.
So why are these sensory clues important? Well, according to Helen Fisher, author of Why Him, Why Her: Finding Real Love by Understanding your Personality Type, women are normally attracted to men who have a different immune system makeup from their own. They subconsciously detect information about a partner’s immune system through smell during kissing. So it's actually strangely practical, as well as being romantic.
