I've wanted my septum pierced for a long time. The only piercings I presently have are both my nipples. The only other piercings I would get would be my bellybutton, perhaps a monroe, tongue, my septum, and my facial lips (maybe two on the bottom or one in the middle on the bottom.) I've also dreamt of having a pierced corset, or perhaps some simple back piercings done with surgical tubing. I've many friends with tattoos and piercings, as Austin, Texas is home to more tattoo shops in the world per capita, so I've really no qualms about anything of that sort.
Someone in this thread stated that what looks good at 20 will not look good at 40. Piercing your septum when you're young usually doesn't have any adverse effects when you're older. The piercing usually closes very easily and leaves no trace that it was there.
Also, I feel that if you're going to be extreme enough to ever get a septum piercing, chances are you wont grow out of it.
Also, you can always get a retainer if you're going for a job that doesn't respond well to your facial jewelry.
It'll hurt like a bitch for a day or so, s you well know. Perhaps you should acquire from vicodins for this endeavor. I know I would.
