Get an ear piercing. If you don't have it already, get your earlobes pierced. Gun piercings aren't that great, especially if you get them done by an unprofessional at the mall. Go to a piercer and get your lobes pierced with a needle. You should wait at least five months before beginning a stretch, to let your ear fully heal.
Getting a piercing at a professional body piercer with a needle is the safest way, and they can pierce your ear at a bigger size than if you got it done with a gun.
