maladaptive sexual behavior, or if you like, the lust, is in part due to faulty thoughts. if you examine your thoughts that lead you to fall, you'll notice, they were just all messed up. "oh, I can just sneak a peak.... oh this doesn't really count... oh whoops"
But the faulty thinking continues when a person falls and continues to attack themselves... it's the same messed up thought patterns, now instead of directly leading to mzl, it leads to depression and sadness, which necessarily lead to the same cycles of destructive sexual behavior.
stop thinking. start doing. HaIkar Hamasseh. the part of the brain that will bring healing is tied to Gcd in ways you never imagined. you have to let Gcd into that space, which means, stop trying to out-think, out-smart, out-control Gcd. Let Him do his work on you. He'll fix you up good, for good. to 120 and beyond in good health.
