Case Study:  A 23 year-old chronic over-masturbator, starting from age 13 at 3 times a day, gets limp during or before intercourse. so, how does it happen?
Reader: 11/29/2010>
Goodday being at my age of 23 i just had sex for the 3 rd time.. and the same outcome.. I'm am getting limp/ loss of erection during or before intercourse... I have masturbated quite often before seeing this girl sometimes 3 times a day starting from when i was around 14.. but have stopped compelety following what you have said but it too soon to notice any results i guess... but what I'm trying to ask is what could be causing this? I am in excellent health i weight train, run, swim.. and all around feel good most of the time...
Thank you for your time....

your chronic over-masturbation results in chronic arterial constriction in your testicles and penis, a natural castration by excessive ejaculation.
In turn,  your testicular function becomes too weak to support your erection and arterial dilation.  Chronic over-masturbation causes neuroplasticity - the deformation of the nervous functions in the hypothalamus-pituitary-adrenal and -testicular axis. You won't get recovery naturally when neuroplasticity of your the hypothalamus-pituitary-adrenal and -testicular axis.
yes, You will  need ViaPal-hGH-J(3-015) and ArgiNOx (1-018), plus FishOil(1000 mg each meal) and Vitamin D 2000 IU,  to help you gradually rejuvenate your neuro-endocrine function and  boost your prostaglandin E-1/E-3 and Nitric Oxide production for improving your testicular and penile blood flow for healing.

Here is what happens:
Over-masturbation/over-ejaculation/excessive-orgasm can castrate the hypothalamus-pituitary-testicular axis by arterial constriction and inflammatory narrowness in your brain and pelvic organs (testicles, prostate, seminal vesicles, and penis) due to excessive release of prolactin, norepinephrine, and epinephrine, excessive binding of norepinephrine/epinephrine on the alpha-adrenergic receptors, the norepinephrine/epinephrine induced excessive prostaglandin E2, and the post-sex deficiency of nitric oxide and prostaglandins E1/E3 production. As a result of arterial constriction and inflammatory narrowness (leading to  arterial thrombosis and atherothrombosis!;  ),  your brain, testicles, penis,  feet and hands get low blood supplies and less androgen hormones and nuerochemicals, but more inflammatory hormone production and stress hormones.  And, it will take a long time for you to get recovery from sexual exhaustion and post-sex inflammation. You may also wonder why your  penis goes limp in the middle of sex.  When your adrenal and testicular function are disabled, you will have to rely on the skin neuroendocrine function to elevate your androgen hormones.

An 18-year old boy's over-masturbation and over-ejaculation results in premature impotence  and anxiety no more sexual orgasm. Why has he failed to heal himself by simply stopping ejaculation?

Why you can not get a natural recovery by self healing from over-masturbation for restoration of  sexual orgasm !
Why this young man can not get a recovery from sexual exhaustion due to over-masturbating, twice a day during late teens - no more sexual orgasm.
How come there are about 5-10% of sexual exhaustion cases that never recover? cut off testicular arteries by prolactin, norepinephrine and/or epinephrine induced arterial constriction and inflammation for the death of the testicular somatic stem cells.
He can not get recovery from sexual exhaustion by simply stopping ejaculation
Chronically over-masturbating 3-6 times a day turned his 19-year old hypothalamus-pituitary-testicular function to be 70 years old for no more sexual orgasm.

His Chronic Over-masturbation experiences for sexual exhaustion symptoms - of course, no more sexual orgasm. Why this young man can not get a recovery from sexual exhaustion
