I have had both my nipples pierced now for over ten years
and I have to say it is great!
They are way more sensitive now and much bigger than the
pimples they were when I did them.
Its a shame some people have bad experiences with this
because I love mine and would shout GO FOR IT!
to anyone asking,
yes they take a while to settle down
but keep them from healing up and they enhance sex like a brand new toy.
