This can only work if you have no doubt that you'll lucid dream. Lets say i were to go through the effort of doing this, and go to sleep worried that it might have been for nothing. If you have a worry that it won't work, then it won't. However, if you genuinely believe that not jacking off that night will give you a lucid dream, or help it, then it will definitely work. It's all based on your mindset, just like Dream Control is.
