Dear Welcome to HCM We understand your concerns I went through your details. Night fall or nocturnal emission cannot give you any health problems or sexual problems in future or present. Nocturnal emissions are natural and is a process which you have very less control over. You must understand why this happens. Let me explain. Your body produces semen whenever you are sexually excited and stores it within the body. thus produced semen is a waste product and body will try to throw it out. If you do not masturbate or engage in sex, the waste cannot be expelled and therefore body s option is to expel it through nocturnal emission or through urination. This is natural and due to this no health problems will happen to you. Your sex power will never get affected. Do not be anxious.
