I personally find eyebrow and lip piercings pretty attractive. Maybe it's just the phase I'm in but I've always loved piercings in general. Not for myself though, I'm way too chicken to do that but on other people I love them. I have not actually ever asked a guy to get a piercing per say and probably won't, it's not that big of a deal to me but if a guy I'm dating does have a piercing it would be a nice bonus for me. I like edgier guys.
