If you want the piercing done, see a professional and pay the money to get it done right the first time. Once you pierce the tissue and screw it up with your attempt to have a navel piercing, you will have left a professional body piercer and mess to fix and it will never look right or pretty.

See a professional body piercer for your piercing needs. Age limits are there for a reason, generally it has to do with development and maturity to look after a piercing correctly.
