How can i get rid of masturbation 'addiction'?

What do you mean?: Almost all men and many women have to enjoy their bodies from time to time or they'll become uncomfortable and can't do the ordinary things they need to (like studying or getting to sleep). This isn't an addiction. If you're obsessed with erotica to the point of missing out on meals, study time, work -- your physician can help with Rx &/or talk; it's fairly common and treatable.
