Researchers at Oxford University have found that kissing acts as a powerful tool for women as it not only helps them evaluate and find their ideal partner but also keep established partners together and builds intimacy among them.
The study aimed to understand why humans, and not animals, frequently kiss each other. It was a survey of 900 people, who were asked to rate the importance of kissing in the early stages of a relationship, before, during and after sex.
Results indicated that women, and not men, rated kissing as more important, suggesting that kissing could perhaps be viewed as a sort of compatibility test.
The study details appear in the Archives of Sexual Behavior.
