Here comes a different opinion...shouldn't every thread have one?
I don't care for the look of them and I would never want one for myself.
I'm not big on jewelry anyway, maybe that's why, and I like the soft smooth feel of my pussy - the combination of the trimmed hair and the shaved labium, and the thought of adding something hard and metal there has no appeal.
I'm happy to show a man where my clit is at if he's having trouble locating it.
The only hard thing I want there is a finger, a cock, or my Hitachi Magic Wand.
