Haha okay thanks Sage, I"ll be sure to get 14g. I wonder if anything bigger would be a problem? I'd imagine that there is a limit to the sizes you can use with out problems. I was thinking 12g originally but 14g will work too.
Montanas Heart: If you put in a 14g it will hurt, I made the mistake of doing that to one of my ears. You can stretch piercings out that way though so if you really want to then you can try it. I wouldn't bother seeing as there is a pretty good variety of sizes these days. Maybe nipples are more flexible than upper ears though, I don't know.
