Teens - Confessions

At age 11 or 12 I started viewing pornographic images and I started masturbating. It wasn't so bad at first, but now it has gotten a lot worse. Just recently, somewhere around November or December of 2011, I got into video pornography. It has made my desire for lust grow, and it has really caused damage on my life. I've gone over 20 days without porn, but I am still facing a problem with masturbation. It is very difficult to overcome. Lust was once my slave, but now I am its slave. Just recently I even humped a pillow and anal masturbated. I lusted after this girl as well, and even had the desire to watch porn. I'm sick of this. God has given me the resources to overcome this, but I constantly reject them because the desire is so strong. One of my best friends, who is a girl, would be crushed if she found out. I need this to be overcome. I hate this. It has turned me into someone I don't want to be. It is very difficult to confess this, but I know that it's for my benefit. If you are reading this, please pray for me. I cannot remain this way.
