IF we're talking 'in real life' gang either is a great indication a woman is into her body & into sexuality in general, so within limits either or both are a great thing to 'discover.'
That said, either should be something left for only 'special someones' to discover... the garish tat or outrageous nose, lip, or brow piercings are ANYTHING but erotic... they're meant to attract attention &/or incite a reaction in people, & the women you see on the net... even the 'amarteurs' who'll never make it 'big' don't need that sort of statement to make people take note.
So I vote for both or either... Tell me Elina Giani doesn't look sexy with that little silver ring. Or that Asia Carrera isn't sexier than a host of other asian women when you see what's glittering 'down there.' Sure it can be taken too far, but that's true of shaving, and ESPECIALLY implants!
Kudos.
