Don't get all worked up guys. It's a preference question. I personally don't care much for them, and I don't enjoy them on film stars or escorts. A band around the upper arm, okay, but I find anything more than that unflattering. And I have to say that I don't understand piercings at all, no matter where they might be. But whoever chooses to do it isn't doing it for me.
I think it is somewhat of a fashion/trendy thing, and will diminish over time or be replaced with something else. I just wonder how it will go for those who have decided on tattoos when the get older and their bodies change.
