Nose Piercings ! XD ?

Hi, I'm 12 years old, 13 in May and most people say I'm really mature for my age. XD

How can I persuade my Mum to let me have my nose pierced, not a ring, just a small stud. I asked her and she said no, (only because of a chance of infection, she said if that wasn't so high, then she'd most likely let me have it done. My dad has said yes though. I've told Mum i'll pay for it and if I or she doesn't like it, then i'll take it out. Any other ideas ?

Also, How do I look after it (try to make sure it doesn't get infected etc.) ?

Any pro's or con's ?

I've had my ear lobes pierced, how would you compare how much that hurts to a nose piercing ?

What exactly is the chance of it ever actually getting infected ?

Can it get pierced with a clear stud ? I've heard you can't because it raises the chance of infection, is this true ? If it is, What can I get it pierced with so that you can hardly see it ?

Please don't say to wait until i'm older or that it looks stupid or something like that ! XD

Thanks alot for your help ! XD

btw. I've tried on stick on gems to see how it looks and my friends say that it suits me :)

And. If you've seen that I've already asked this question a couple of times, It's because I need as many opinions and advice as possible XD
