>If I fap just between x days it will be fine
This is such hot garbage. First because once you gone a long time you realize that you don't need to fap at all to feel satisfied.
Second, that you will be wasting willpower and torturing yourself counting the days until you can PMO, this is literally just glorifying the act while setting yourself for failure.
Third, that again once you've gone a long time, you realize that fapping to porn is not even enjoyable to begin with, you really have to push the limits and train yourself to be a degenerate like that.
If you still want to cum, I wouldn't say its that bad at all fapping once in a while, just keep out of the porn garbage. And speaking of which OP, I don't its that bad doing it with your gf online, just keep in mind to not overdo it as well, since you're getting used to video/pictures stimuli versus the real thing, just make sure you meet regularly in real life and make up for the time lost.
