Earings I don't have a problem with unless there are, like, seven per ear. navel piercings I don't have much of a problem with. I do have a problem with the following: noses, tougues, lips, eyelids, fingers, toes, nipples, bottom, kidneys, jugular, ahem....a place I can't mention, picture frames, cardboard boxes, scalp, monkeys, lemons, shoe.
Coloring hair is perfectly fine. I don't color mine, but i've thought about blue or red. I've done it at a soccer game once, but it was cheap stuff that would come off with sweat.
