Congrats on your new metal Lilith! I'd like to get some facial piercings, but it's not allowed with my employer, heh...
I started with 14G in my belly and nips. Stretched my nips up to 12G 6 months later. I think it probably depends on nipple size some and how deep you're going to get them done, my piercist didn't recommend getting them done originally with as big of a gauge as a 12 though. I think it has a lot to do with proportion, although I do like bigger (well, smaller really, you know how that backwards thing goes, heh) rings on men. To each their own!

P.S. Thanks Xanne Yep, belly ring peeking out there too, as well as one of my inkjobs! I'm decorated all over!
