There are people who will tell you that masturbation is not wrong. I'm not going to commit to that, but I will share some thoughts. I struggled with this same thing for my whole youth. I have been married 31 years, learned what real sex is from God and my wife, and gave her into the hands of Jesus as she died. Flat out: there are no scriptures against masturbating. If someone believes it is wrong, he does so based on his experience following Jesus as Scriptures have directed him. If he believes it is not wrong, he does so based on his experience following Jesus as Scriptures have directed him.
In the Bible times, you would have been married at age 14, after your father helped you arrange a marriage, and build a house for you and your wife to live in, while he taught you in private about sex as you pounded each nail. We have changed society, keeping men from marrying until way later. We are not following God's original plan. I do not believe that 17 year old men are "addicted to masturbation". I believe their bodies are confused by a social order. And I believe Satan is ready to mount accusations and guilt onto feelings that have no outlet.
On the one hand, your body needs to let chemicals out if it is to be ready to please your wife when you do marry. This should, by right, be happening during dreams at night, giving you a little washing job when you wake up. Just look at how many seeds a tree puts out every spring; yet only one or two ever become other trees. God is a God of abundance, and you have more than you need for your life.
What is wrong, that I am sure of, is fantasizing about one girl or another. Every fantasy is an expectation of what you will want a wife to be, and God probably has other ideas of what you will need. If it must come out, keep away from pornography, and keep away from having sex with anyone. These will just hurt your married life later on.
God's plan is that you find out who you are in Him, and you let Him choose the right woman for you. Work on that as best as you can. Sex is for loving one woman with all your body, and all your labor, as well as with all your heart. It's love that will create a new beginning for someone in the next generation.
So the bottom line: what if it won't stop? I don't have an answer, even at my age. The people who condemn masturbation condemn it because it is self-aggrandizement. I have never experienced that, and I almost wonder if there are not two kinds of masturbation, based on what I hear them say.
Again, I can't tell you what to do, and I have put off posting this, wishing I could do better. But at least I'm sharing as much (or little) as life has taught me.
