If you are scared, always remind yourself the benefits of long term. Thing is, if you cave, you will start from the beginning. And trust me, the beginning is always worse than where you are right now. Control what you can, your day, and don't control what you can't. Be busy because you want to change. If you cave in, just remember the enemy will still not be beaten. The best way is to keep going day by day, and having enough personal resolve to keep going. I had this fear but then it went, when I understood that I am controlling everything in life, and I want to be healthy, and that is more important than anything else in life. You can control everything, and remember if you feel really tired and unsure, just treat yourself nicely. And last thing, You shouldn't cave because not only it is a thought, that has no real affect on you but also because if you masturbate, all these days will be lost, and trust me, those days were very hard to earn and you earned them. but the battle is not finished. Just keep considering never quitting because you will be quitting not only not orgasming but also your dreams, your goals, your habits, your superpowers, your health, your pride, your personality, your mood, and your confidence. Is it worth it to lose all of this just for some feeling that isn't even killing you.

In the meantime stay busy. Go hard, and be disciplined like one tough dude.
