The kiss is one of the most intimate manifestations of the human being. Although it is not exclusive to our species, the emotional and sexual sense that we give to the act of sharing a kiss is as mysterious as it is relevant to our life.
When the first kiss was given, we do not know exactly, but what we do know is that from the scientific point of view a kiss can be enough to determine if a person really attracts you or not.
Think about it, imagine a boy you like and imagine that you kiss him passionately, now think of someone else for whom you do not feel attraction and imagine that you also kiss him. Which one do you like and which one does not?
According to Wendy Hill, an expert in neuroscience, the kiss is a way of testing the other person (literally) because sharing a kiss is shared saliva and in that saliva is an impressive load of sex hormones that drive our reproduction.
So if a man kisses you with passion and above all with a lot of humidity, it is because you seem really attractive sexually and probably also sentimentally. In this sense, a good kiss can be enough for two people to fall in love.
*The lips are one of the most sensitive parts of our body, hence the brain more easily register a pleasant or unpleasant stimulus. When we kiss we are testing the other person and the chemistry between them; If you go out with a boy and his first kiss is disappointing and tasteless, it's time to look for someone else.
Of course, a relationship implies many other things that go beyond sex, but remember that the most incredible thing is when you have the whole package: love, admiration, friendship and attraction.
You can be with someone who is good but with whom you do not share a real attraction or can be with someone who likes you in all the ways and also makes you feel a revolution of reactions in your body. I would prefer the second one.
If your partner does not usually kiss you or you feel that the kisses that are given are simple and without true connection, then it is likely that you are next to someone who cares for you but does not feel a real sexual attraction to you. So pay attention to the kisses that your boy gives you and you will discover what he really feels.*
