Honestly in my opinion, I think that those who have a lot of piercings, it is just their choice. Some pictures I have seen of people with piercings (usually like all over their faces, ears, tongue, practically all over their body) actually look quite creepy and look like they went over board but their body.

I have only 2 piercings. I have had my ears pierced once and that was when I was very young and when I turned 16 or 17 I think, I got my ears pierced a second time. Unlike some others in my family, I really rather not get any other part of my body pierced. My ears being pierced twice, is good enough for me.
