The real way to deal with those urges

Just acccept them. Recognise them as just thoughts and feelings, as your brain playing with you and trying to trick you. Your brain is just rationalizing why you should fap, for whatever reason. But you have to control that bitch and not let it trick you again. You have to understand that you are NOT your thoughts and your feelings, rather you are just an inspector of them. Laugh at your brain for even trying to do this to you. And then do what's right and stand by your values. This is the key to true self discipline and self mastery.
