Why do you get nipple erections?

Answer 1

Men have what is referred to as libido, and that means their sex drive that is due to the hormone testosterone. Also men are very visually stimulated as opposed to women who are stimulated in more subtle and more complex ways.

So, nature designed males to become stimulated and ready for sex with any visual queue that a female was ready for fertilization. One of the adaptations that human females made was to develop fatty tissue in their breasts so that they look like they are lactating all the time, a sign of fertility.

So it's not so much that men see a woman's nipples that turns them on, but that they see the shape of the female breast with the nipple that gives them the instinct to become aroused.

BTW: Human females are the only ones that have developed this ability to mimic their capacity for fertility visually. So, human males have just been following along and changing with them in order to keep our species alive.
