I just got my septum pierced and I got it at standard 16 ga. Its pierced w little high but its just fine. I was wondering, once healed, does it sink? Meaning, does the piercing become heavier to the point where it moves the piercing itself? And I don't want to stretch my piercing, I just want a longer horseshoe, what can I do to get one? Or do I have to stretch the piercing?
