Not a fan of extensive piercings, particularly the lips, nipples and clit-hood. If it's some place I'd be likely to nibble IRL, I'm not a fan of it - I just don't like the taste of metal.
You get used to it on the earlobes. Also, not a huge fan of nose piercings - with the way my nose reacts to pollen, I can't imagine having something like that in my nostril all the time. Probably feels like a huge booger.
