Humans are the only mammals who sexualize the breasts. Many men and women find breast very sexually attractive. We stimulate them during foreplay, we wear clothes to accentuate them, we are the only primate females who’s breasts enlarge at puberty. But why?
Well there are a couple of potential hypotheses. One of them is that breasts are used to store fat and so, evolutionarily speaking (man I hate that phrase), a woman with big breasts is healthy and will likely be able to bring a male’s offspring to term. An other hypothesis is that most primates have rear entry sex as opposed to the face to face intercourse that we humans often have. A lot of primate females have very pronounced rear ends to attract a mate and some scientists believe that the breasts are enlarged to mimic the enlarged bums of other primate females.

Anywho, Larry Young and Brian Alexander aren’t so sure about those two theories. They think that the bond that breast feeding infants and their mothers have is directly related to why we love breasts. When babies breast feed the mothers brain releases oxytocin. (For those who don’t know, oxytocin is a really wonderful feel-good happy chemical that your body can produce). This oxytocin makes the mother focus more intensely on the baby, forming a strong emotional and physiologically enforced connection.
When a partner touches, massages or nibbles a woman’s breasts, it sparks the same series of brain events as nursing. Oxytocin focuses the brain’s attention to the partner’s face, smell, and voice. The combination of oxytocin release from breast stimulation, and the surge of dopamine from the excitement of foreplay and face-to-face sex, help create an association of the lover’s face and eyes with the pleasurable feelings, building a bond in the women’s brain.
It’s an interesting idea, and probably has a lot to do with it, but it feels like it’s not the whole story. To me it explains why women may like having their breasts stimulated but I don’t think that “because sucking her nipple made your mom high when you were a baby,” is the reason why humans are so obsessed with breasts. I’ll keep you posted if I find out anything else, true believers.
