Why do men like women's first round?

Men 's excessive desires in the first round of women have been unjustly explained by scientists, claiming that this is a very ordinary human instinct.

The mammary gland is characteristic of mammals for raising children, but for humans it also has a huge sexual role. Researchers have long predicted that the mammary gland accumulation of women is this reason. Anthropologist Owen Lovejoy argues that evolution affects both male and female genitalia, to promote association. In this hypothesis, not only women's breasts, but also men's " boys ", because they are relatively large for their bodies.

A previous hypothesis also suggests that breast development is a sign of youthfulness, fertility, a promising mate. The study found that men like big breasts, small waist, big buttocks, hourglass physique. A 2004 study even found that large breasts women with mid-cycle estradiol levels could increase fertility.

However, big breasts are not always worshiped by men. In a 1951 study with 191 different cultures, anthropologist Clellan Ford and zoologist Frank Beach reported that breasts are an important part of every man's affection in 13 cultures. Among these, 9 cultures like big breasts. The cultures of Azande and Ganda in Africa, like the long chest, the saggy, the fruity shape. The other two cultures, Maasai of Africa and Manus in the South Pacific, like a toned chest, not necessarily big and attractive .

Even in the same culture, the interest is different. A 2011 study of men's preference for breast size, symmetry and size, dark circles in Papua New Guine, Samoa and New Zealand found that men from Papua New Guinea preferred likes breasts with larger dark circles, compared to men from two other islands.

Men like the first round of women because the neurological effects form when they step through puberty.

New research by psychiatrist professor Larry Young, Emory University (USA), suggests that human evolution has turned an instinct when breastfeeding becomes an agent to strengthen husband and wife relationships. And, men are like babies, like to be sucked.

When a nursing woman, their nipples will be stimulated during that time and their brains will produce oxytocin, which enhances the mother's attention and affection.

But after years of research, scientists have found that this link is not just exclusive to babies. Nipple stimulation when " love " is similar to impact on the private area. When men touch the chest, oxytoxin will be produced in the female brain similar to when they feed their babies, helping her to increase her attention to the partner. In other words, men can increase their attractiveness to women by stimulating a woman's first round.

According to Professor Young, the feeling of liking female breasts is a neurological effect formed in men when they step through puberty . He said: " Evolution has determined that this is a neurological mechanism in men that causes them to be attracted to the first round, because this will help them create a connection with women and vice versa with women. In other words, men have evolved to carry out this behavior to simulate the link between mother and child .

So the question here is why does this hobby only occur in humans but not on other lactating mammals? Professor Young said that the reason is simply that humans can create a husband and wife relationship , while 97% of other mammals do not. " In addition, it is possible that humans are upright animals and have the ability to have face-to-face sexual intercourse, which in turn has more opportunities to act on chest touching. Therefore, perhaps nature Our sexuality has allowed for more access to breasts, "concluded Young.
