I've been stretching for 6 or 7 years now. I have a 4g and a 3/4" on my left ear and 6g cartilage, 6g, 2g, 6g, 3/4" on my right ear.
I also have two industrials, my eyebrow, bridge, two septums, medusa, tongue, angel kiss, snakebites, tongue, and three other lip piercings that I don't wear jewelry in but they haven't closed up so I still play around with them sometimes.
