Question

What use are a man's nipples to him? and why do they puff up at times?

Answer 1

s*x, male or female is  decided in  the womb. this sensitive nipple is hence provided for both sexes.

Answer 2

Nipples are a sensitive spot in the body so a man can get aroused by having his nipples rubbed or pinched

Answer 3

In the embryonic stage of development, boys and girls all have the same parts.  Then they move around to where they're eventually going to be and assume whatever their ultimate function is.  Guys' nipples just are kind of leftovers.  But they're wired the same as women's, that is on the same "circuit" as our s*x organs (either p***s or clitoris) and made out of the same stuff, called erectile tissue.  I guess the idea is to encourage women to nurse their babies by making it feel so good.  Men just get the benefit without the work.
