completely normal, called a "wet dream". Feel free to google it :)
Its not cum in your boxers, its pre-cum. It is a wet dream you are having and as a result you wake up with erections. It is completely normal.
Like what everyone else said it's just a wet dream. You'll eventually stop having this happen to you after awhile. So don't worry about it. You could try to masturbate before you go to sleep it might help stop you from having a wet dream.
At your age you should be whackin it as much as you can, it's just another daily routine like having a cup of coffee! Enjoy it while you're young as you'll miss it when you get older :)
