I guess some guys might like it, but I don't find face piercings attractive. A very small one at the side of the nose won't completely turn me off but doesn't really do anything for me. Lip and eyebrow piercings I find distracting.
I don't really like piercings--no, not even a belly button ring : ) Now, I would NOT mind/judge a girl for having them; I could be very good friends with a girl who had them, and if we really clicked, I'd even consider a relationship. But in terms of the aesthetic value of piercings, I think they add nothing to, and most usually distract from, a woman's natural beauty.
You know guys like belly button rings? Interesting because a woman with extra holes not put in her body by mother nature, aren't a turn on to me at all, no matter where they are located. That is not to say I find them repulsive, but there isn't a piercing out there that I 'like' Just thought you might like to know that since you seem to want to generalize all guys.
It all depends on the person. I personally don't like them cause they ruin the girl's facial features. It's all in the eye of the beholder, but I'd guess that the majority of us guys don't like them. I've asked my friends if they think that's attractive and most of them would agree that it's not.
I have 2 lip piercings and a lot of people have commented on how nice they look. I also have 6 tattoos (including a full back piece) and probably only have received one negative comment about my tattoos and piercings. I think if you take the time to consider how such a mod will affect your looks and the placement of it, it can actually look nice. Yes piercings leave a scar, and tattoos are permanent but if you don't buy into the whole thing then leave well alone.
