Question on discouraging temptations

Hi fellow NoFappers. I’m 18 days into NoFap. I always come here looking for suggestions or moreover to discourage my brain from temptations of PMO. Although I’ve been strictly off P since day 1, I still have some doubt in terms of what exactly should I starve my brain of. So exactly three times out of 18 days I have M very lightly (no P or O) just to feel normal again and it occurred to me whether this is also a thing that I should stop myself from doing during the reboot. So to conclude, my question is whether I should completely shut my brain off from any intentional physical sensation and starve it for the arousal I get from M so it does not get any stimulus in terms of pleasure and in turn boosting recovery?
