You should learn to control your urges. You must, if you don’t want to keep falling back to it!
That kind of discipline will help you overall in everything, so, I find this much more useful than asking any entity to take care of your problem - which, in itself may be again only another excuse to continue the same behaviour and not doing anything of your own.
Write down a list of why it’s bad for you. Find more reasons than the obvious ones, if you need to. Then add on another column on this list, the positive aspects of not masturbating. From then on, use this list, to remind you consequently of the consequences and of the two sides of actions you can take, so that you train yourself refraining from any harmful behaviour.
This is only one way to achieve discipline, there are more ways, that can help. But I strongly believe, it is YOU who should take action and not someone else for you!
