I know what you are feeling. I had an addiction to masturbation before I became saved. The Lord personally stepped in and helped me stop it for good. Satan tempted me with it many times as well after I quit, but what kept me away from it was my desire to honor God more than do things that displeased Him. My advice to you is pray to the Lord to protect you and give you strength. Remember that we are in Christ, and we are to live to be like Him. You don't want to give Satan something to be happy about, you want him to lose. The longer you stay away from it, the less he will tempt you with it, and the "feeling" of it will start fading faster.
