When I was catholic, I used to avoid fapping. I struggled, but I managed to get a routine of 2 weeks without fapping before relapsing on the 15th day.
I never experienced the benefits of no fap. The only thing no fap did for me was that I was horny all the time and I was going to school/college, giving presentations in front of everybody with a raging boner.
