A New Theory on Why Straight Men Love Breasts

What are breasts but bags of flesh and fat with some tissue and glands? When you think of it in biological terms, it’s quite silly to think of some men’s obsession with them.

But the allure of breasts is a fact of life and now Professor Larry Young at Emory University, who studies the neurological basis of complex social behaviors, has a new theory on we love breasts.

You might have attributed our love of breasts to breastfeeding. It is logical that breasts once meant bonding and nutrition to us when we were infants. Larger breasts can mean more milk — something desirable in a mate. Just like how many women prefer tall men, we have the desire to reproduce with the best specimens. But Young thinks further than that — and more sexual. “When a woman’s nipples are stimulated during breast-feeding, the neurochemical oxytocin, otherwise known as the ‘love drug’, floods her brain, helping to focus her attention and affection on her baby,” says Live Science.

Those of us who are lucky know that nipple play can be arousing. Young says that man’s brain has evolved to subconsciously recognize this stimulation. In other words, men know about oxytocin and that it will make women focus their attention on their sexual partner just like with the nursing baby. “Evolution has selected for this brain organization in men that makes them attracted to the breasts in a sexual context, because the outcome is that it activates the female bonding circuit, making women feel more bonded with him. It’s a behavior that males have evolved in order to stimulate the female’s maternal bonding circuitry,” Young says.

This science doesn’t mean you can stare away and blame your biology, though. Respect the breast.
