This is a pay site but there are lots of free stories that tell peoples experiences with different type piercings. And there are actually alot of free pictures too.

One thing stands out from reading any of the stories at that site........ have them done by a professional!!

And since each person is different, nipple rings don't hurt for everybody. Guess it depends on how sensitive you are to start with.

Good luck!! Keep us posted on how it went.
