I have query about masturbation .I am really depressed as I came to know about semen .I have read that masturbation releases dopamine in the brain which is harmful for the brain in many ways. Semen is produces 24*7 inside the body then why losing semen is a massive loss for the body. Does masturbation cause nervous disabilities. Does masturbation destroys brain chemistry. Does masturbation overproduce neurochemicals like dopamine, endorphins, acetylcholine. Acetylcholine is very important for cognitive function of brain and when we masturbate we release excessive acetylcholine in brain which reduces brain capacity of learning. Doctor please help me out .I am a student and I am a good student but these days I cannot concentrate on my studies as these things keeps revolving around my mind. Please sir or madam help out of this loop. I will be very thankful for your helpful activity.
