The doctor explained that glands are not muscles, and do not need exercise. Glands secrete fluids all on their own (e.g., wet dreams), and manual intervention is simply not needed. Therefore, if a man cares to take a time-out, he can rest assured that his body will meet his ejaculation needs without his intervention. The forum member added: Since I have not had a wet dream for a decade or more (always masturbated) I asked the doctor, “What if I don’t have a wet dream?” His reply was, “Well then, you no longer need to ejaculate.
As we investigated, we discovered research showing that too much ejaculation can cause lingering physiological changes. When men engaged in a “ten-day depletion experience,” ejaculating an average of 2.4 times per day, their sperm output remained below pre-depletion levels for more than five months. It’s quite possible that there are other effects occurring in the brain, which haven’t been uncovered yet. The research hasn’t been done.
