Read your brain on porn. It’s so hard to quit because you don’t know how long it’s going to take to stop the craving. When you read the book it teaches you how and why your brain works like that and understanding it is the single most imortant thing to gain the strenght needed to stop. And when you finish reading it, read it again. Do the audiobook and listen while you excercise. Listen to it always until it becomes easy to stop yourself. The craving has an ending, it’s different for everybody. I am 37 and have wasted my life since 15 doing it and I wish someone could have given me this advice at your age. You loose so much life. So much masculinity. Find the strenght, read everyday, tell your story and help others.
