Is it normal that i have developed a severe addiction to this?

I did not grow up wanting to end up this way, it sort of just snuck up on me. Now I have a really bad problem with masturbating too frequently. I am not sure what the normal amount of masturbation is really. I am thinking like once a day maybe? I have reached a new low. I jerk off about 5 to 6 times a day, sometimes more and sometimes less. This is starting to feel more like a problem to me now. What should I do to stop masturbating so much? It's as if my brain is constantly telling me to rub one out.
