Scientists have never satisfactorily explained men's curious breast fixation, but theorists are gonna theorize. Mammary glands are a defining feature of mammals, but humans seem unique in granting mammaries a large sexual role. That's not to say interest in nipples is entirely unheard of elsewhere in the animal kingdom: In the book "Biological Exuberance: Animal Homosexuality and Natural Diversity" Stonewall Inn Editions, , Canadian biologist Bruce Bagemihl notes that a couple of primate species, including humanity's close relative the bonobo, have been seen stimulating their own nipples while masturbating.

As predicted, men with higher SOI-R scores unrestricted generally gave higher ratings than did men who scored lower on the SOI-R restricted , but the difference was significant only at larger breast sizes. We also found that medium to large sizes were rated as the most attractive by both male groups and that viewing angle changed rating of female attractiveness and breast presented in oblique view were rated generally higher than in side view. The results of the study indicate that sociosexuality influences male perception of female breast attractiveness and confirm that accentuation of female-specific physical traits produces a stronger response in unrestricted than in restricted men. Men are attracted to a number of physical characteristics in women, including youth cues, face shape, symmetry, waist-to-hip ratio WHR , distribution of fat reserves, and other secondary sexual traits Barber, ; Buss, ; Singh, , Female breasts are one of the secondary sexual traits that attract male attention and influence male judgments of attractiveness.
If Jessica Simpson is bent on making her second marriage work, this may not be the best way to go about it. Men have always been attracted to large breasts, and her husband-to-be, former NFL player Eric Johnson, is probably no different. But what about poor Eric? Most women spend their lives worrying that their breasts are too small, which explains why breast augmentation is a far more common procedure than breast reduction.
