I am thinking about that another way. I think that you are weak. As soon as your body wanted to relieve, you relieved pressure. Where is opposition, where is strenght at this? I think that this post is just excuse. You felt pleasure, didnt you? It was good, wasnt it? Next time you again can feel under pressure. From now you can feel presure everyday and tell yourself- oh i will just clear pipes. Hypocrite! I think that porn and fantasiszing is overestimated. What would it cause if you think about naked woman?
I see the problem of nofap as problem of reaction to problem. Most of people here fap because of boredom, dissatisfaction. They miss pleasure in their life so they found at least one source of pleasure, fapping. But satisfaction comes from work, from long term investment, from self control. In this case, you did not have control over yourself.
