Hey just thought I'd add that when I had my nose pierced (about 4 or 5 months ago) I was asked if I'd prefer a ring or a stud - so I'm assuming he would have given me a ring if I'd asked for it, but he didn't seem too enthusiastic about them, and said that studs always heal better.
I was also advised to keep it in for at least 3 months, not the 6 weeks that lots of people seem to be talking about - noses take a long time to heal and need looking after very carefully because their position leaves them very open to bacteria and gunk getting in the way. He said that even if it feels healed, it probably won't be, and it's when you start faffing about with it, changing it before it's ready that many people get infections, bumps and scars - apparently it's very unusual for anything to go wrong or for it to leave any nasty scars if you have it done properly, don't touch it unnecessarily or with unsanitised hands, clean it regularly (I did twice a day with saline solution for about 6 weeks, then only once a day for a while) and make sure it's got proper jewellery in it! If you look after it properly to start with then you'll have a nice hole for you to do whatever you like with afterwards, there's nothing worse than a ring in a hole that looks like it's coming out of a wart!
Also, side note - I understand your parents, but permission from your boyfriend!? It's your body, not his!
Good luck with your piercing, they're lots of fun!
