Dr Richards I am a 20 year old male I have been masturbating since age of 13 between 4-10 times daily recently it has gotten to point where the penis has shrunk 2-3 inches and semen is very watery and erections are very weak is there any way to get back to where I was or improve myself?

ANSWER
13 years of severe oversmasturbation burned too much vital neurochemicals, depleted acetylcholine, serotonin, dopamine, and GABA levels, increased inflammatory and stress response, and created negative neuroplasticity to sustain the cycle.

In the specific case, if these are the only symptoms experienced, the imbalance locked the proper hypothalamic-pituitary-adrenal-testicular functioning for less androgens.

“is there any way to get back to where I was or improve myself?”

Yes, in the specific case one will strongly benefit from:
A combination of Alpha-Amino, Alpha-AGH, Multi-Alpha, and Ultra-Purified-FishOil this should directly boost the hypothalamic-pituitary-adrenal-testicular functioning and restore the altered homeostasis, restoring erection power. Note that experiencing anxiety, depression, or any other symptom is indicative of imbalances of certain neurotransmitters and should inform me to alter the advice accordingly.

Testicle cooling to additionally address lowered androgens may also be considered.

Exercise, proper diet, positive attitude, negative ion exposure, massages, and sexual abstinence for 2 to 4 weeks will prove beneficial.
