Why men like boobs?

Larry Jung and Brian Alexander, who recently released the book "The chemistry between us: love, sex and the science of attraction", separated the emotional, biological and cultural reasons why men like women's breasts.

The authors believe that heterosexual men are so fascinated with the female breast for a simple hormone that is released during breastfeeding, which helps to establish a strong and robust relationship between mother and baby, but which later serves to create a strong bond between lovers.

"Men are the only male among mammals fascinated by breasts in a sexual way. Women are among only females mammals whose breast increase during puberty, independently of pregnancy. We are also the only species in which males cuddle, massaged and orally stimulate the breasts during foreplay and sex"said Jung. 

Research has shown that stimulation of the breasts increases sexual arousal in 82 percent of women.
"Boys do not learn on the playground that breasts are something you should be interested. It is a biological and deeply embedded in our brains. Interestingly, our research shows that men, if they see breasts or even something that just reminds us of the breast, such as bra, unconsciously begin to make bad choices"said Jung.

Biologists believe that, because the breasts are most part made ​​up of fat, it means that a woman is healthy and that is a good candidate for the procreation of children.   

However, the authors of the study believe that the male fascination with female breasts unconscious evolutionary tendency, which pushes us towards creating strong relationships.
