Kissing is the sweetest way to show love. Among couples the kissing style differs between men and women. "Women tend to use kissing to create a bond with their partners, and to assess them as potential mates. Meanwhile, men use kissing as a means to an end," said Susan Hughes, a psychologist at Albright College in Pennsylvania, told Life's Little Mysteries.
"Whereas females felt there was a greater likelihood that kissing should lead to sex with a long-term partner than a short-term partner, males felt that in either instance, kissing should lead to sex," wrote the researchers.
Psychologists hypothesize that males "perceive a greater wetness or salivary exchange during kissing as an index of the female's sexual arousal/receptivity, similar to the act of sexual intercourse," wrote Hughes.
