It's a bit of a turn off for me, I like the more innocent looking characters and a piercing disturbs that image. The same for tattoos. Maybe except a Belly button piercing.
I always think women looked better in like the 70s and 80s when very few had tattoos or non-ear piercings. Of course the unshaved vag was it's own unattractive thing.
I can take it or leave it. Don't need it for a chick to be hot, doesn't make things that much hotter for me if she has them anywhere. Then again, I don't mind extra holes on a woman anyway
