Body piercing as become fashionable amongst youngsters (and some oldsters). It involves inserting metal objects in to places in the body that really don’t need to have metal objects in them. Some people have become so fascinated by this practice that they have “extreme” piercings. Self-piercing is very dangerous, and you should NOT do it. Using a safety pin is also even more dangerous when self-piercing. You never know what might happen. It may get infected easily, since the sterilization methods aren't present. Get it done professionally! Please don't try this at home!
