Smell, voice pitch and face symmetry might be unconscious detectors of attractiveness, but if you're trying to consciously assess the future of a relationship, Dr. Berman says there's one surefire way. "You really learn a lot from a kiss. ... Sixty-six percent of women say they would dump a guy after a bad first kiss," she says. "It's not only because you're getting that good whiff of him so you're seeing if you like the way he smells. All your senses are engaged, and you get a sense of his sensuality, his connection, whether he's a take-charge kind of guy or more of a stepping back kind."
When it comes to relationships, Dr. Berman says kissing frequency is a direct indicator of happiness. "It turns out that couples who kiss and cuddle regularly are eight times less likely to be stressed and depressed than couples who don't get that," she says. "You have to have a minimum of a 10-second kiss every day."
