It's certainly a personal thing in terms of likes and dislikes. I fall in line with Plan9. I don't care for the visual interruption in that area and it seems that the risk of infection and other problems might be a bit high. I however do not own a clit but I would love to operate one on a more fequent basis
. That said if a willing owner were pierced I don't think I'd make a big deal out of it.
