To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex.
Human nipples appear in the third or fourth week of development, well before the sex characteristics (The sex hormones start to assert themselves at seven weeks.)

The male breast is a rudimentary version of a female breast just as a clitoris is a rudimentary version of the male penis. Since men do not give birth they don't need such a functioning organ to breast-feed.

During development, the fetus is neither a male or female.

i think it has something to do with us all being the same sex as embryos and then going in one direction or another.

hmm...so it would look like a female breast if the man turned out to be gay and he had breast implants...
