Nipple piercings????

I’ve wanted to get nipple piercings for a couple of months now and my best friend says she’d get hers done with me... My boyfriend isn’t a huge fan of it (which is fine... his nipples aren’t the ones getting pierced so his opinion isn’t the determining factor in whether I’m getting it done or not). Does anyone have any advice? Do you regret it? How bad did it hurt? I got a rib tattoo a couple months ago and that wasn’t bad at all.. would I be able to handle it? I’ve gotten my ears pierced before and they didn’t hurt. Any after care advice? How does breastfeeding work with them?
