Men like wet kisses with more tongue action, as revealed by Anthropologist Helen Fisher of Rutgers University. Other possibility could be that men are trying to transfer testosterone to the woman to stimulate her. "Men see kissing early in a relationship directly as a step to copulation," she said.
Kisses could also be a means to judge the possible mate, as believed by Wendy Hill, a neuroscientist at Lafayette College in Easton, Pennsylvania. It was also stated by Fisher that the men and women either declared their first kiss as "the kiss of death" or the blossoming of a new relationship.
The research involved a personality test that measured four universal temperaments by using statistics from 40,000 people on the Internet dating site Chemistry.com. Each of the temperament was linked to activity levels of the brain chemicals dopamine/norepinephrine, serotonin, testosterone, and estrogen/oxytocin.
Fisher concluded that an individual's temperament judged the kind of mate they choose, thus, enhancing the belief that love involves chemical reactions in the brain.
"People sing for love; they dance for love; they write about love; live for, kill, and die for love," Fisher told National Geographic News.
"It's a wonderful addiction when [a relationship is] working well, but perfectly horrible when it's working poorly," she added.AGENCIES
