I think your old enough to not ask for anything. I'm 16 and I just feel bad and guilty asking for things from people if somebody wants to get you something it's so much better when they do it just cause they want to than you asking them to get you something. now I they asked you what you want that's another story. in that case ask for something you have been wanton and keep in mind what you think the person can afford :)
Your old enough . Im 14 and i dont ask for anything for my birthday or christmas . Im thankful for the thinks i have and when someone tells me what do i want , i say "its okay , you dont have to get me anything"
