Some people have smoking addictions, some people have drinking addictions...and well...some people have masturbation addictions. It's just another addiction that requires help if the person who is addicted feels it's impacting their life.
I don't think mastrabation is evil but it can be bad when used addictivly. I think it can be problamatic when used in conjuction with porn. You are on the right track in your thinking
Mind over matter.

I would suggest that you look at porn that is a complete turn off. If you like regular sex, try looking at something that is taboo like grandma sex or sex with animals.
