As far as gage you probably want to start with a 14 gage or maybe a 12. Then if you feel you want bigger later on you can buy taper kit and gage them up. I hope this helps you in your concideration of getting it done.

It is pretty painful to get done initially but bearable. If you are going to get it done find a reputable piercer to do it. The healing process can be a little painful as well and strict cleaning regiments are key to healthy piercings.

I have had mine done and had them for 30 years what do you want to know? I would be glad to help.
