Good Masturbation or Bad?

I am nineteen years old, and I can't seem to help myself from masturbating. I don't know what it is, but I think it has now become an addiction. I can not stop from doing it. Every time I see a girl who is fine, I always think about touching myself. I do it every day, sometimes twice a day. My problem is that I wish the orgasm would be more powerful. I think the reason I do this so much is because the orgasm is not powerful enough.
