Well, if you aren’t satisfied with the explanation that we kiss because it feels good, you are at the right place. Of course, the most obvious answer is to express love, but there is more to a ‘liplock’ than just showing affection. We found a few people on Quora who answered ‘Why do we kiss’ and we bet, you definitely didn’t know these! Read them here!
Will Wister answers on Quora: The lips are tremendously sensitive and create an unparalleled sense of intimacy. I've heard hookers say they would rather copulate with somebody than kiss them because the intensity of kissing somebody is so meaningful. There's tremendous intimacy. Even the genitals do not have the sensitivity that the lips have.
Bob Anderson answers on Quora: Kissing is particularly sensual and delivers a great "feel good" sensation. No muss, no fuss, ready to go immediately (no batteries required).
Natalie Engelbrecht answers on Quora: Men tend to initiate French kissing and research suggests this is because saliva contains testosterone and this increases the sex drive of their mate. Furthermore, men are able to sense a woman’s level of estrogen which is a predictor of her fertility. While men are not selective in terms of kissing, women are very choosy. This is because on an evolutionary level women were looking for a mate to raise their offspring with, and kissing could be an unconscious but accurate way for women to assess the immune compatibility of a mate before she invests too much time and energy in him.
Doug Girard answers on Quora: Kissing increases levels of dopamine (a neurotransmitter involved in pleasure and reinforcement) and oxytocin (a hormone involved in attachment and intimacy processes). Kissing decreases levels of cortisol (the body's main stress hormone).
Yuliy Valenko answers on Quora: Your lips contain lots of nerves. So when you kiss, your senses are mostly focused on the person you're kissing. This gives a feeling of unity and harmony, thus improves trust between both of you. As far as I know, trust is an essential ingredient for a good and sustainable relationship. For women, it is a confirmation of appreciation and for men, it's the expectation of sexual satisfaction.
