Since I am unlikely to ever know someone with them, I'm asking these questions at large -
a) do nipple piercings make the nipples more sensitive?
b) if the answer to a is yes, does it enhance the enjoyment of
c) will the nipples still function for breastfeeding if the
piercings are removed? (I think yes, because there are milk
ducts in the areola, but I don't know)
