i experienced the same thing 10 days before. so i reset the counter for better accountability.
Step1: decide not to fap
since decided not to watch porn at all, be it xvideos, spankbang etc, didnt venture there.
Step2: Now no porn. But urges felt. because brain is used to function in a certain mode. its difficult to change in a single day. this is where deceptions occur.
brain deceive that youtube videos are cool, so better watch it.
Step3: Convincing the self to watch youtube for one last time. becoz there is no harm there.
But actually your brain doesnt distinguish between hardcore porn or mild erotic. brain chemicals are one and the same.
Step4: Nightfall - it occurs because of thinking alone. it is not an automatic phenomenon.
since exposed to youtube but nofap, brain triggers at the night time. nerves in the penis lose control and fap.
So the danger lurks not in porn but the interpretation of triggering content in the brain. the trigger is severe in porn but milder in youtube. Ultimately, the trigger is the same and it will result in fappiing or nightfall. so my suggestion is to stay away from streaming websites permanently. Till the rewiring in the brain takes place, it is difficult to conquer addiction.
This is my own personal experience. hope it helps.
