No length gains

This is my opinion and my experience about jerking off after P.E..
I’ve had no negative issues with my gains from jerking off (especially afterwards)
If anything masturbation is a positive reinforcement to your gains as because at an erect state , blood is filling the newly formed cells/tissue after P.E exercise.. Promoting growth.

REMEMBER: this is my opinion. But as regards to experience.. No I have not seen any negative effects from masturbation after hanging.

I am going to start edging but my problem is to control my need of cumming during edging.

I have to search more about edging and premature ejaculation techniques.
