Are men's nipples really that sensitive? I wouldn't think so. What would make them so? -Brad
Dear Brad, The sensitivity of a person's nipples is very individual, regardless of a person's sex. Both men and women may have nipples that are incredibly sensitive or that have no erotic response whatsoever. This gender similarity is due to the fact that the nipples of both men and women are surrounded by smooth muscle fibers that cause them to become erect, e.g., when aroused or cold. When stimulated, they fill with blood, becoming even more sensitive for some people.
While the stereotype is that men cannot have sensitive nipples, some men beg to differ. Many of them have nipples that are actually more sensitive than those of their female counterparts. Many of them enjoy nipple stimulation.
