Kissing on the lips is one of the most intimate acts of physical affection. It is an act of love, passion, and desire that has been around for centuries. But why do we kiss on the lips? Scientists have been trying to answer this question for years and have come up with a few theories.
One theory is that kissing on the lips is a way to test out potential mates. Through kissing, we can assess the other person’s hygiene, health, and even genetic compatibility. It is believed that kissing on the lips helps us determine if the other person is a good match for us.
Another theory is that kissing on the lips releases hormones that make us feel good. When we kiss, our bodies release oxytocin, a hormone that helps us bond with the other person. It also increases our feelings of trust and closeness.
The mouth is also a gateway to the whole body. It is linked to our gut microbiome and skin, so when we kiss it may have a positive impact on the microbiome in our whole body, even affecting our brain and mood.
Kissing can also be a way to express our love and commitment to our partner. It is a way to show our partner that we care about them and that we are willing to make a commitment to them.
Finally, kissing on the lips can be a way to show our partner that we are attracted to them. It is a way to express our desire and passion for them.
Kissing on the lips is a complex act that has been around for centuries. It is a way to test out potential mates, express our love and commitment, and show our partner that we are attracted to them. It also has a positive impact on our microbiome and our mood. So, the next time you kiss your partner, remember that it is more than just a physical act, it is a way to express your love and commitment.
