Nipples of Steel

I think if women were meant to breastfeed or pump then we should have been made with nipples of steel.  Really, there shouldn't be any nerve endings in our nipples.  I don't have very sensitive nipples in normal, non-pumping mode, so I can't imagine what they would feel like if I did.

I mean, I know why they are.  If they didn't have nerve ending we wouldn't know if the baby was latched on correctly or if they bit down, but then maybe we should have super fast healing nipples then. I bet Super Woman had nipples of steal.
