Hello there children and how are you today? Anyway had some rum and coke and started thinking about my nipples, why do we have them? Is it due to a design blueprint when we are developing in the womb? I think not, I think that the real reason men have nipples (and well you know boobs) is this: When we get fat and old we develop MAN BOOBS! And women find man boobs a bit of a turn off, so the reason we have nipples (and boobs) is really the bodys way of telling you to get into shape and become a virile man again so w can spread the seed.
