Yes, frequent masturbation is bad for you. Each time you masturbate you are stimulating your neurotransmitters in an artificial way, similar to drugs or any substance that is not a natural food. The more you stimulate these neurotransmitters by masturbating, the less you produce them, which is exactly what happens if you use drugs regularly. When these neurotransmitters are out of balance, you are not yourself and you become weak and meager in your mind. That masturbation is harmless is a lie perpetuated by people that want to keep you enslaved in a world where you do not have the mental faculties to see the truth or stand up for yourself. Stop making excuses for jerking off and start waking up to the truth!
