there are harmful physical and psychological problems as a result of over-masturbation, as noted below:
Anxiety: Masturbation puts people in a very comfortable position and therefore when there is a partner to go with, there are anxiety issues relating to size, stamina, and ways to please the partner. The performance anxiety which is quite common can be very high in over-masturbators. Both males and females with this habit can face sexual exhaustion and recurrent genital infections also.
Chronic fatigue: Masturbation induces the production of the steroid hormone, cortisol. This increases the rate of metabolism and therefore leads to an exhausted and fatigued feeling.
Back pain or discomfort: Over masturbation reduces the production of oxytocin, DHEA,
testosterone and DHT. The depletion of these neurochemicals triggers a release of the inflammatory hormone prostaglandin E2, which is one source for lower back pain.
Groin and/or testicular discomfort and pain: There is a loop between the pituitary-adrenal-testicular glands, which is responsible for production of oxytocin and testosterone production. These have anti-inflammatory properties and over-masturbation tends to reduce this production. This leads to a groin pain which can extend into the testicles and continue chronically.
Penis shrinkage: When started early in life, the amount of growth hormones in the body reduces with over-masturbation. This leads to inadequate amount of hormones for the penis to grow to its full size, leading to a smaller organ.
