Ever wonder why men have nipples? Apparently they have no use for them do they, but would men look any different without those nipples? Well the reason men have nipples is because during development the embryo follows a female template until about six weeks, thats when the male chromosome kicks in for the development of the male embryo. Thats when the male enbryo begins to develop all its male characteristics (although I'm not sure about some guys hehe). The finished result being men left with nipples and also some breast tissue. Wonder if this would explain why men like looking at breasts (the female kind of course) perhaps because they missed out on having them heheh
