iv had it, and yes, it hurts when it gets bumped in the begining. look at the portfolios of the person that is doing it. look for them to be even. if the needle goes in sideways the piercing will be sideways.. i had mine somewhat streached, i could put a pencil in it. in the end, iv taken it out. it closed up pretty quick, so i could only get a very small GA. in it now if i tried.. i think it looks cool, so give it a shot while your young.
