People kiss because they are trying to satisfy a hunger within them, a hunger for passion and the need to touch someone else, to wrap your arms around the one you love that drives two lovers to each other.. This craving for human contact is instinctive.. It comes naturally and cannot be taught.. what can be learnt however, is how to kiss.. kissing is easy to learn.. most people do not actually read up on kissing, preferring to hone their technique by trial and error..kissing is pleasant because the teeth, jawbones and lips are full of nerves, and when the lips meet an electric current is generated..
