I heard the following in audio version of Outwitting the Devil written in 1938 (although the book was so controversial it didn't get published until recently. After some Googling I found the quote on a PUA forum: Napoleon: Just what damage is there in the over-indulgence of sex? (Ie porn addiction can be related to this) Devil: The greatest damage is that it depletes the source of a man's driving force, and wastes, without adequate compensation, man's creative energy. It dissipates energy needed by nature to maintain physical health. Sex is nature's most therapeutic force. It depletes the magnetic energy which is the source of an attractive, pleasing personality. It removes the sparkle from one's eyes and sets up discord in the tone of one's voice. it destroys enthusiasm, subdues ambition, and leads inevitably to the habit of drifting on all subjects. He then goes on about what is known today as "sexual energy transmutation" Devil: Controlled sex supplies the magnetic force that attracts people to one another. It is the most important factor of a pleasing personality. It gives quality to the tone of one's voice and enables one to convey through the voice any feeling desired. it serves, as nothing else can serve, to give motive-power to one's desires. It keeps the nervous system charged with the energy needed to carry on the work of maintaining the body. It sharpens the imagination and enables one to create useful ideas. It gives quickness and definiteness to one's physical and mental movements. It gives one persistence and perseverance in the pursuit of one's major purpose in life. It is a great antidote for fear. It gives one immunity against discouragement. It helps to master laziness and procrastination. It gives one physical and mental endurance while undergoing any form of opposition or defeat. It gives one the fighting qualities necessary under all circumstances for self-defense. In brief, it makes winners not quitters. Incredible! Especially around tone of voice, energy and attraction! The secret has been known for years! This was written in 1938.
