How can i reduce frequent nightfall or wet dreams?

Nocturnal Emissions: You cannot. It is impossible to even try. These are subconscious and there is absolutely no medical reason that you should not have them. If you masturbate or are sexually active then the prostate gland will be less likely to have to expel excess semen to keep the prostate healthy.

Why do you ask?: Neel, you're a grown man -- 28 years old. This is something you should have gotten settled as a teen. You've got a wonderful adult body, the ability to make a partner happy, to be a loving husband and beloved father. You either have emissions during the day by yourself or with a partner, or at night. Your choice. You should enjoy and treasure the experience whenever it happens.
