Sexual Role. Breast play an important role in the sexual habits of humans. Breast is one of the secondary sex characteristics and plays an important role in sexual attraction to his partner, and individual pleasure. Breasts are also part of the oldest woman's body viewed by the opposite sex.
Breast is a woman's sexual attractiveness. When women have breast sexy and beautiful, of course they would be proud. Breasts also become sexual attractiveness of men who see its shape (sex appeal). So it is important to maintaining the beauty of the breast.
Other functions. The experts stated that there was no breast at another living being female than in humans which has a large variety, relative to all parts of the body, when not lactating humans are the only primates that have a bloated breasts all the time. This indicates that the outer shape of the breast connect to factors other than breastfeeding.

This can result in slowly in the human male sex to evolve to respond to the signs are more obvious for the presence of ovulation.
