Honestly, the possibilities of “No Fap” aren’t well understood, but could potentially be VERY far reaching.
Beyond the extreme desensitization of dopamine receptors, androgen receptor down-regulation and the surge/constant elevated levels of prolactin, you could also argue that in terms of non-physical psychology, it’s equally bad.
In the realm of the mind, everything is relative. Constantly rewarding your psyche of its most primal desire with a fake substitute is the ultimate self-created short circuit in manhood.
