yeah i've gauged mine numerous times and let them grow back.. at different times i had some sixes.. grew back... 2's.. grew back... 4's.. grew back.. now i just rock studs.. i've gauged them so many times (improperly) that the inside is pretty scared up so it's hard to stretch and hurts like a mother.. of course no one but myself can tell that it's scared.. i don't meant they look gross or anything.. you can just feel it on the inside.
