I don't know what to ask for for my birthday

Money.

depending what sports u like,maybe ask for tickets to see a sports match

or...

dvds of your fave movies/cds of your fave singers
take a horseback riding trail with vrienden of family

How about an ax? If you're in a sports contest, chop up the competition. If you're out doing country stuff, slaughter the cows. If you're being harassed, teach those sex-offending bastards a lesson. It's good for tons of other stuff, too.
