Do you have to licensed to do body piercing?

In order to become a professional piercer you must first obtain an apprenticeship with someone who has the skills you are looking to learn. They will teach you different techniques and styles in which to perform the piercing, they will teach you basic anatomy so as to avoid large nerves, and they will also teach you how to deal with people. You need to be an apprentice for at least one year or at the very least perform every piercing you feel comfortable doing at least 15 times. When I say that you need to find someone that will be able to teach you the skills you want to learn and also when I say piercings you are comfortable with I mean that you need to decide what your boundries are. If you are male and feel uncomfortable piercing below the neck (save for a navel) then you need to make these boundries clear, if you're a female and don't mind piercing anything then jump in and hope your mentor will perform all the piercings you want to learn. If you have qualms about piercing the genitals of the opposite or same sex then you need to make these clear as well. Also, some advanced studies and anatomy will help you along your path.
