Face and mouth
Oddly, it all starts with a tilt to the right – 80% of people angle their heads this way when they start kissing.
You are communicating and suddenly you feel a sensory explosion!
The lips become 200 times more sensitive than the highly sensitive fingertips.
Meanwhile, your nose dives into the odor of the opposite side, which emits a subtle chemical attraction that can intensify your arousal.
Rapid clicking uses two pairs of muscles, but eager kissing involves about 24 facial muscles and 100 other body muscles as well.
(A violent kiss burns 100 calories.)
Your salivary glands begin exercising their own, by pumping in more saliva.
During real contact with the tongue, about nine cubic millimeters of your saliva finds its way into the mouth of the other end (and vice versa).
Butter from the above: This juice is packed with up to 1 billion bacteria cells, but the good news is that 95% of them are harmless.
The kiss can send shock waves that pass through the body, which increase blood flow to certain areas.
This leads to hardening of the nipples, expansion and contraction of the stomach, and finally, tingling in the genitals.
Adrenal glands (adjacent to the kidney)
The adrenal glands release adrenaline, which leads to an increased heart rate, heavy breathing, and sweaty palms.
Physical arousal may trigger the brain to release dopamine, a neurotransmitter associated with pleasure.
Meanwhile, negative emotions are closed off in other areas of the brain.
Also, closing your lip can provoke your pituitary gland (and the other end’s gland) to release the hormone oxytocin.
It’s called the “attachment hormone,” and at this point you may have already formed an emotional attachment.
Any type of activity can reduce stress and increase happiness.
Relevant people who accept more are, and often times, more likely to have good, long-lasting relationships.
