I can't speak for how it feels, but a good friend of mine who I've played around with has hers pierced, and I've got to say, I find it sexy. Then again, I don't think it's any more or less sexy than not having it pierced.
I suppose like most things, it's a body image issue, if you think it (and you) look good, then you'll project that. If you're self concious about it, that'll show too.

Keep in mind, this is coming from a guy with no piercings or tatoos.
