While it is easy to purchase a body piercing kit on the Internet, it is not a good idea to pierce yourself. Piercing professionals have had years of experience piercing. Professional body piercers usually start with an apprenticeship, where they learn how to properly pierce from someone that's been in the business for a long time. Body piercing, especially piercing the tongue, nose, and genitals, can be extremely dangerous and cause permanent damage if performed by an inexperienced person. It is best to get your piercings done by someone who knows what they're doing.
