nipple piercings

good idea or bad idea? my boyfriend so badly wants me to get them done, he even offered to pay for it and buy me a new bra so i can be more comfortable. ive got 11 tattoos and 12 piercings. in your experience how painful is it?

*UPDATE*

I got my nipples pierced. over all id say it was a 7 out of 10. I love them though. Totally worth the pain.

*UPDATE 2*

After having my nipples pierced for a week they don't hurt at all. I barely notice them. I'm so happy I went through with it. I feel so confident and sexy now. It's amazing how 2 little piercings can change so much. Would highly reccomend!!
