Hi, think about this for awhile. When you consume bad food, your body rejects it and tries to get rid of it. You get a running tummy, vomiting etc. Same thing with your mind. When you think bad thoughts, your mind tries to get rid of it. So when you watch porn, your mind tries to get rid of the impurities which causes you to take out your semen. But if you think good and positive thoughts, the mind is at ease and the temptations are weak. Experiment with this and tell me what you think.
