Kissing your loved one is by far one of the most important moments in people's lives. It should be both passionate and really professionally executed in order the emotions evoked by it were beautiful. To start with, what exactly happens during the kissing ?1. Heart of love- the centre of love, that manages every sexual activity is called hypothalamus.2. Your lover's appearance- the image associated with your fine memories and the nervous impulse produced by them, goes to the hypothalamus.3. Your loved one's scent- ferromons being given off by him or her increase activity of the neurons in the hypothalamus, accelerating the feeling of excitement4. Your skin is sweating in order to prevent the body, in which blood is boiling, to be overheated.5. Under the influence of adrenaline the heart beats faster, so the lungs must supply the body with more oxygen- hence the deeper and irregular breathing occures.6. Arteries supply organs with blood faster than veins can get rid of the used blood from organs.7. The core of the suprarenal glands begins to produce adrenaline and noradrenaline, which make the heart euforic and prepare muscles to work harder.8. Adrenaline slows down digestion, the stomach is overloaded, so to speak. we can interpret this symptom as "feeling of the butterflies in your stomach".9. Genilalia are better supplied with blood. Men's penises erect and women's vaginas are moisterized.
