During fetal development, all babies start out developing as girls. Then,the Y chromosome that makes a boy causes a surge in testosterone in the fetus' body that changes female sex organs into male sex organs. By that time, the body has already developed nipples.
In fact, there are documented cases of men nursing their babies. Usually, this only happens when the mother dies in childbirth or shortly thereafter. So the nipples *can* work, too.

Mainly, guys have nipples because women have nipples. All embryos (the developing fetus) start out as female. Gender becomes determined around six weeks of development as a result of hormone "baths," triggered by the genetic character of the cells' chromosomes. So, the basic physiological structures are initially there, with the hormones released around the sixth week of development determining whether an embryo will develop female or male characteristics.
Nipples in men have no specific purpose, but can be very responsive to sexual stimulation. Nipples (in both men and women) are filled with many nerve endings and can be quite sensitive. They can be an erotic area (or erogenous zone) for both women and men and respond to sexual touch and stimulation. Breasts are one of the defining structures that identify all mammals in the animal kingdom, and nipples occur in both the female and male of the species. It is interesting that in the higher mammals more closely related to humans — bonobo apes, chimpanzees, and gorillas, for example — nipples are quite prominently developed in the male.

Every single fetus in the womb begins it's life as a female.
A penis is just an extended clitoris.
