Kissing is sometimes called "swapping spit". That's a fairly unromantic way to describe it, to say the least. But it turns out to be pretty accurate!

The kissers are finding out vital information about each other's DNA through the contents of their saliva. If the clues they are seeking cannot be detected after the first long pash, that can spell the end of the relationship.

When I started reading it, I thought "How unromantic", but its a true way to find perfect match sometimes.

Even though I do not know about the scientific view, I feel that the very first pash plays a major role in cementing a relationship as it gives a better understanding of the physical intimacy between a couple.
