I've had 30+ piercings. I'm down to 3 now (nose, conch and PA). I'm a piercer by trade.

My lobes were at 1.25" at one point. They're now down to about 7/16" but I rarely wear jewellery in them. Conch is at 6g, it was dermal punched instead of being pierced. Heals up MUCH better and faster this way. My PA is at 6g as well. Nipples were done at 10g but took too long to heal so I took them out.
