Would you say you enjoy tasting people?Apparently smelling each other’s butts is “frowned upon” in the human species, so we’ve resorted to tasting one another.
These chemical signals might join other cues we get from the closeness and intimacy of kissing and combine to give an instant, hard-wired impression of whether this person is the right one with whom to mate.
There’s a slew of chemical communication going on, an amount that puts ethernet to shame.
At the moment of a kiss, there is a very complicated exchange of all kinds of different information,” says Gallup. Some of it is in chemical form. Contained in male saliva, for example, are small amounts of testosterone, which is known to boost libido in both genders.
What are we learning from all this mouth to mouth data transmission?
Out of 12 cranial nerves, five of them are picking up the data from around the mouth. It is built to pick up the most sensitive feelings—the most intricate tastes and smells and touch and temperature. And when you’re kissing somebody, you can really hear them and see them and feel them. ….Other researchers note that kissing is biology’s way of determining who in nature you are most genetically compatible with. “At the moment of the kiss, there are hard-wired mechanisms that assess health, reproductive status and genetic compatibility,”
