I went another month without masturbation and it couldn't get easier than this. Controlling the mind is very important.
Well done bro, keep going. You're right, it's all about guarding your mind. Choosing what you focus on and what you dismiss. As a man thinketh so shall he be
You are right. The right mindset and matured decisions are key. Even more important than cold showers, no sugar, no caffeine. Sure all those things can help a lot to a beginner but without the right mindset, those things don't guarantee success.
Also, have some spiritual minds such as thinking about god and watch EWTN because that will be effective to kill the urges. Some people may work and some do not.
