Depends on what people you mean. Some people still make the link between piercings/tattoos and prison or "bad people" or whatever.
I just think it's a nice way to "decorate" yourself, like earrings or a necklace, but then it's just a piercing. I like them on people who can pull them off.
I'm personally not a big fan of piercings in the face, just because I wouldn't get them personally, but if they fit someones looks and personality, I don't see anything "wrong" with it and other people shouldn't judge based on someones piercings or tattoos or whatever.
It depends on your age range. Right now I wound't really be worried about those piercings and I'd go with it and probably find it hot. But in 10 years I know I wouldn't find it hot anymore on a guy. So right now, yeah I'd say those can be hot and I'd say pierced guy equals edgy and sexy.
I tend to not enjoy them because they only look good in certain faces. If you can pull it off, cool. But, I wouldn't think of them as something long-term. Like, I have a nose stud and it's not really flashy or whatever, and a lot of people have them. Other than that, I don't see a pierced guy as having much potential in life. I mean, where do you see people with piercings in life? bumming around on the streets, mostly.
Well in the middle ages, some women would keep toothpicks in their mouths at parties so strangers wouldn't suddenly kiss them. That bit of history is what I think of when I see metal objects in peoples mouths :)
