This is all I have to say on the topic: Yes there are legitimately real benefits to NoFap. That are sure to help both men and women in life. Although it's bold to say that this one thing can stop a lifetime of poor speaking habits and negative mental conditioning. It sure could assist - especially with increased testosterone and mental clarity - but to be the be-all-end-all? Don't know. If your stutter is coming back "full force" after relapsing, it'll be because you've developed no solid breathing/relaxation/mental habits and patterns. Which essentially is the foundation to improving your speech and overall quality of life. Just saying.
