It will adversely impact you if you do it to porn or remember porn while doing it. But if you don?t, this may depend on how old you are and how highly you associate fapping with porn. For many of the guys under 30 fapping is so highly associated with porn watching that it?s hard to split the two and they?ve found benefits from completely abstaining long term. For them fapping brings back too many porn associations and conditioning. However, for the older guys that started to fap before high speed Internet porn existed, it is less of an issue. They associate it with porn far less if at all and developed more innocent habits of doing it without the aid of porn. Even then doing it a lot would probably hold up the reboot. So depends which category you are in. Personally for me, 49 days into reboot, I?ve found doing it once every two or so without porn actually helps revive me a bit. But then I?m late 30s.
