I'm a pretty big piercing enthusiast, I've had many a piercings in my face, I don't really agree that they're painful, or that you should even bother with a numbing agent, seeing as they really don't work.
For anyone out there thinking about getting their ears pierced DO NOT get it done with a gun! You wonder why you remember it hurting so much as a child? Because they pierce your ear by shooting the stud straight through your lobe. Look at the back of your studs... those things are blunt. Scar tissue ftw. Get it done with a needle, way less painful

I have my ears stretched to 30mm and the 20 odd stretches it took me to get them to that size does not compare the the pain of gunning your ears. I promise!
Apart from that, parents are pretty dead against piercings, my mom agreed to let me get my nose pierced when I turned 16, and she hated it. From then on in I just started coming home with piercings in my face, and amazingly, she had the most problem with my septum piercing, which you could never see, and I wouldn't have to worry about everyone seeing the scar (it's the piercing inside your nose)
I wouldn't tell anyone to go about getting piercings the same way I did.. I stressed out my mom heaps. Talk to them about it first! at least that way they don't have a heart attack when they see you with two rings in your lip.
They don't want us to scar up our pretty little faces
