I don't know the laws in your state, but he probable can't until he is 18. And you have to be the same age as well. And if you two are intimate, he can be charged with statutory rape if your parents push it. Tread very lightly. Also check in to begin emancipated with your state court.
But my personal advise is to wait. It may be hard, but it solves all kinds of trouble down the road. At 18, you can do almost anything you want with in limits. You have to be 21, to total be free of parental involvement.
Good Luck Hon. And I know that there are some of the others that will argue with me, but I've been there before. I speak my mind.
