Stretching my ears? (Multiple questions!)?

Well you had alot of questions so Idk if im going to be able to answer them all. But I'm only 16 and my ears are 00. And I found that spraying bactine which is a spray for infections you can buy at drug stores it takes away the burn if ur ear is burning, and it helps prevent infection. I also clean my ears and gauges reguraly with hydrogen peroxide. I really don't know what that ball in the ear thing is, but I have one on my ear, it doesn't hurt but its been in my ear for a while since I started gauging. And one last thing, don't stick to tapers forever they'll cause ur ears to "blowout", start using the plugs if ur going to go bigger. Tapers arent good only when ur ear is small.
