-Nipples are especially sensitive and are a source of sexual stimuli, even for many men.
-Nipples are the result of an efficient plan of embryonic development. Human embryos contain characteristics of both sexes at first, because they all have basically the same genetic information. It is design economy. For example, in all human embryos, at first both the mullerian duct system (female) and the wolffian duct system (male) develop, because both sexes have the genetic information for these structures. Incidentally, this refutes the urban myth that human embryos "start out female."
