New research overturns commonly held beliefs about men
Regardless how many sexual partners you've had, you may still benefit from figuring out the extent to which you're wired for pair bonding. Being a pair-bonder, by the way, doesn't guarantee "happily ever after." It means socially monogamous: having the capacity to fall in love and the desire to bond, at least for a time. In contrast, most mammal species are like bonobo chimps and rats; they mate and move on. The reasons for the differences lie in brain structure.
Despite our capacity for promiscuity, we humans are a pair-bonding species. It shows up in our powerful hankering for touch and ongoing companionship—and makes perfect sense, as our offspring benefit from parents who hang around with each other for more than one estrous cycle. (For a solid analysis of human pair bonding, see "Your Sexy Brain" in The Compass of Pleasure.) As with any trait, however, there are always outliers (atypical individuals). So how do you know where you are on the pair-bonder spectrum? And what does it mean in terms of finding contentment?
