Why masturbation decrease PE gains ?

I was reading in few places in thunders place that masturbation is decreasing the gains of PE but none of the places explained why.

I really want to hear the reason of it [because I am pretty addicted and I do try to decrease it in general but its could give me a little extra boost to do so]

There isn’t any legitimate proof it slows gains. It didn’t for me.

I disagree with that theory.

Whereas I am not aware of any proof (or even a solid theory) that masturbation hinders gains, I would encourage anyone to really focus on the edging/ballooning/PONR journey with any time they have blocked-off for masturbation. Making PONR your personal servant has great PE and non-PE benefits, and it’s something that needs to be maintained (a skill rather than a state one attains).
