Your masturbation pattern is extreme. In my many years of counseling sex addicts who mostly have that same high pattern over several years, most are physically medicating a chemical imbalance as well as possible psychological instability. Go on the Internet and search out the symptoms for depression, bipolar, cyclothymia, or manic depression. If you fit any of the criteria, see a psychiatrist immediately. Even if you get stable medically, you have probably also created a sex addiction problem. I would also suggest a 12 Step support group and reading on sex addiction. Healing now could be a great gift you give to your future in so many ways.
