Why do we kiss?

Kissing is utterly underrated. A two hour make out session always trumps going all the way. A study out of Albright College in Pennsylvania found that humans kiss to assess a mate--much like taking a tiny bite of a strange dish. Breath and taste of saliva affect our decision, which is not surprising. They also found that 85% of women would not have sex with a partner if they didn’t kiss first. Not shocking: more than half of the men said that they couldn’t give a fig if a smooch preceded sex.
But what about technique? Men like moist, wet open-mouthed kisses, the study found. They need more saliva to assess a mate. Now that explains why the Rage’s first kiss felt so slimy.
