I've been wanting to get my belly button piercing done really badly for a long time now, But my parents doesn't have any money so I want to do it myself I just need numbing stuff. I also want to become a professional piercer when I grow up.

Well don't start by doing/getting a home piercing. It's a fantastic way to get a surface piercing, which will be difficult to heal anyway, infected or worse.

A good piercing at a reputable shop shouldn't cost more than $50. Start saving. And do NOT use aspercreme. It's 1. not sterile and 2. not for internal use. Best way to get a piercing not to HURT?? Get it done by a pro, using a breathing technique.
