“[W]hat transpires during an initial kiss can have a profound effect on the future of that relationship,” Dr. Gallup and his co-authors wrote in a paper published in the journal Evolutionary Psychology.
Further study by Gallup and colleagues of kissing behavior among over 1,000 college students found that the function of kissing differs for Mars and Venus. Based on the responses to three questionnaires--and much prior research--the psychologists believe that women use kissing as a way to assess a potential mate and to grok the status of a relationship with their current partner. Men, however, “appear to use kissing to increase the likelihood of having sex.” (Are you shocked?)
Other survey results: Fifty three percent of men said they would have sex with someone without kissing them first, while less than 15% of women would. And men answering the survey were “much more likely” than women to do the horizontal mambo with someone they considered a bad kisser.
