I was reading the "Sexuality In The Aetiology Of The Neuroses (1898)" and found this. I thought you guys might like it.

"Masturbation is far commoner among grown-up girls and mature men than is generally supposed, and it has a harmful effect not only by producing neurasthenic symptoms, but also because it keeps the patients under the weight of what they feel to be a disgraceful secret."

"Left to himself, the masturbator is accustomed, whenever something happens that depresses him, to return to his convenient form of satisfaction and relapse."

"If masturbation is the cause of neurasthenia in youth, and if, later on, it acquires aetiological significance for anxiety neurosis as well, by reason of the reduction of potency which it brings about, then the prevention of masturbation in both sexes is a task that deserves more attention than it has received."

Sigmund Freud

Edit: I added the year of his work (1898). Thats for how long people know the risks of Fapping.
