I personally didn't do NoFap (I actually quit porn in 2011 before I heard of NoFap) but just cut out porn, and masturbation naturally eased away (for the most part) as I wasn't tempted to sit at a computer for hours on end with the novelty which is way, way more stimulating than any real-life partner. So I was just NoPorn, but I still think I experienced the changes most guys describe at Reddit.
There's one other benefit to NoFap (or just NoPorn) rarely noted: TIME. I wasted so much time on it that I was amazed at how much longer my days seemed (in a good way) when I quit porn. I quit smoking at the same time, and going out for cigarette breaks for 45 minutes per day was also eating up tons of time. Between quitting the two vices, my life felt so much longer and more fulfilling (in retrospect, I think quitting porn was probably the more beneficial addition-by-subtraction of the two).
