Masturbation is a symptom rather than a cause of lethargy, ennui and general lazy behavior. The goal should be control over your own impulses rather than completely shutting down said impulse. Fap less and not don't fap. Not just because of the golden rule of moderation but because the point of nofap isn't gnostic magical qualities of semen retention, it is the self discipline to not pursue pleasure endlessly. If you have that self discipline then you will be able to apply that self discipline elsewhere. Masturbation doesn't cause a lack of discipline, it is a symptom of it.
It's not a scientific book but I recommend you read Courtesans and Fishcakes. It deals with the Greek philosophy on moderation and moral/immoral behavior regarding food drink and sex. And you can see in a 1990s book the literal concept of the coombrain as the Greeks had it 2000 plus years ago. The synopsis is that moderation indulges your appetite (Sexual or food) when it is necessary, and not when it is not necessary or beyond the necessary amount. Masturbation every other day, every few days, once a week or whatever is your bodily urge. Once a day or more than once a day is most likely beyond the bodily urge. I say this as a coombrainer.
The author, or an ancient greek, likens such behavior to a vase with a hole in its bottom side - what you fill it with (Drink, food, sex) cannot satisfy and so you seek it more and more. Self discipline is plugging the hole. It is not voiding the vase of the filling, but rather stopping the filling from being wasted and being satisfied with only what is necessary.
How much cooming is necessary is the question.
