Nipple Piercings??

Okay, so my husband told me that he really wishes that I had nipple piercings. I've always been kinda curious and interested in them but I've always gone back and forth about getting them. Can anyone who has them give me some advice? How bad was the pain? How long did they take to heal? How long did it take to get them? How much did it cost? Do you ever regret them? Thank you so much in advance!!!
