"So you know that researchers theorize that pretty much everything we do, relationship-wise, is biologically based. And kissing is no exception. In fact, a new book says that men and women kiss very differently for different reasons... This article in TIME talks about a new book called The Science of Kissing: What Our Lips Are Telling Us, which says that kssing apparently boosts levels of neurotransmitters such as &amp;quot;dopamine (which is involved in craving and desire) and serotonin (which elevates mood and can help spark obsessive thoughts about a partner). It also causes a jump in oxytocin, the so-called &amp;quot;love hormone.&amp;quot; And kissing is so important to us, shows the research, that &amp;quot;59% of men and 66% of women say they have ended a budding relationship because of a bad kiss.&amp;quot; Apparently even this goes back to biology--when we kiss, our sense of smell picks up on clues about the other person&amp;#x27;s DNA to help figure out if his genetic code would produce genetically diverse children. So here are a few ways men and women smooch differently, according to researchers--and speculation as to why: Women: * More likely to insist on kissing before, during and after sex. * Use kissing throughout the relationship to continually evaluate the state of the relationship. Men: * More likely to prefer a French kiss. The theory? Men have small amounts of testosterone in their saliva, which, after awhile, could help raise testosterone levels in a woman and increase her libido. * Men use kissing to &amp;quot;weed out unsuitable mates&amp;quot;--or make themselves more attractive to &amp;quot;suitable&amp;quot; mates.
