Why We Kiss

Gallup's research suggests that men and women have different agendas when it comes to kissing, an act that occurs in 95 percent of human societies and is believed to have been first recorded in Vedic Sanskrit texts around 1500 B.C. in India.
For men, kissing is more often used as a means to an end -- namely, to gain sexual access. Men also are more likely to literally kiss and make up, using kissing to attempt reconciliation.
Women on the other hand use kissing as a mate-assessment technique, Gallup notes. They subconsciously evaluate mating potential from the chemicals in their partner's saliva and breath, for instance.
Women also use kissing as a bonding gesture, as well as to monitor the status of the relationship. If her partner's kissing frequency or technique suddenly changes, that perhaps is a sign of his waning interest.
Other gender differences uncovered by Gallup's research:
• Men show a greater preference for tongue contact and open-mouth kisses.
• Men are more willing than women to have sex with someone without kissing, as well as to have sex with someone they are not attracted to or consider to be a bad kisser.
• Women place more importance on kissing throughout a relationship, whereas men place less importance on it as the relationship progresses.
