Why Men Love Breasts
Put in their simplest (if not so flattering) description, those protruding sacks of fat drooping from women's chests wouldn’t seem to have any special appeal.
But it’s pretty clear from movies, advertising and lingerie that they do – and scientists (being scientific) have been trying to explain just why that is for centuries. Mammary glands are a defining feature of mammals, but humans seem almost unique in granting mammaries a large sexual role.
Researchers have long speculated that humans evolved the fatty deposits around the female mammary glands for sexual reasons. A long-standing theory holds that breasts evolved as a way to signal to men that the woman was nutritionally advantaged and youthful -- and thus, a promising mate.
Studies finding that men prefer large breasts and a high waist-to-hip ratio bolster the notion that an hourglass shape communicates youth and fertility.
Of course, most men attracted to breasts don’t seem to be thinking about fertility -- or anything beyond their immediate vision. To explain that, other theorists view the attraction as cultural. They believe that men aren't so much biologically drawn to breasts as trained from an early age to find them erotic.
If that’s the case, we can all agree that the training has been enormously successful.
