04>Ejaculation or orgasm burns the neurochemicals and androgen hormones in the brain and cerebrospinal fluid.
As a result, the acetylcholine, dopamine, and serotonin level in the brain and nervous systems drops; dopamine is sharply converted into the stress neurohormones norepinephrine and epinephrine for the sympathetic nervous system to induce orgasmic contraction, and for ejaculation and post-ejaculation prostate pains, post-orgasm muscle pains/cramps and post-orgasm muscle/joint stiffness after the prostaglandin E-1 synthesis in the tissue is blocked by excessive norepinephrine and epinephrine in the bloodstream; the androgen hormones are excessively converted into DHT, leading to exhaustion of the adrenal and testicular (ovarian, for women) function which are supposed to produce more androgen hormones to burn during sex; the pituitary gland releases excessive prolactin without oxytocin when the brain's dopamine and androgen hormones become too low; finally, the semen production mechanism will be disabled due to a lack of the cerebrospinal fluid, a weak acetylcholine/parasympathetic nervous function for the liver, prostate, adrenal glands, kidneys and testicles, and a weak dopamine nervous function for the testicles and seminal vesicles, and an excessive prolactin, norepinephrine and epinephrine in the bloodstream.  Don't let excessive prolactin, norepinephrine and epinephrine in the post-ejaculation or post-orgasm state shut down your sexual function and disable your penile erection. If you can block the release of the prolactin  by reducing (or even blocking) the dopamine-norepinephrine-epinephrine conversion and retaining a high-level of androgen hormones in the hypothalamus/pituitary gland, you can continue to erect your penis and to have sex all day long without sexual exhaustion.  If you cannot, you have to change your lovemaking and ejaculation strategy for one and only one ejaculation a day while having sex all day long; otherwise, you will start to experience sexual exhaustion symptoms.   I have collected tons of the sexual exhaustion examples due to over-masturbation, over-ejaculation or/and excessive orgasm in the following links, and so far nobody can escape from the consequence of the sexual destruction -

The hair rooting cells will be damaged by maintaining a constantly  excessive DHT, prolactin, norepinephrine and epinephrine level in the bloodstream, and the hair falls off.
You have to de-stress your body, reduce the DHT, prolactin, norepinephrine and epinephrine level,  and dilate your blood vessels to improve your scalp blood circulation for the sake of your hair. 
I have 2 suggestions for you:
1. Take ViaPal-hGH-P (3-010), 5-HTP (2-001), Androbolic (2-009), Borage Oil and Fish Oil; eat a lot of sea foods (salmon head, shrimps, lobsters and oysters), sea weeds (yes! you need the vegetable from the ocean), vegetables, seeds and nuts; drink a lot of juices - apply, orange, tomato, berry....

Of course, you can not find animal penis, testicle and blood (for the whole body chemistry!) in the US market, but you may be able to get deer penis, testicles, blood and antler during hunting seasons. If you need extra androgen hormones - hGH, DHEA, androstenedione, androstenediol, testosterone,  DHT or more, your own first morning pee is the best. This is called Urine Therapy which contains all natural steroids  produced by your own neuro-endocrine system during your night sleeping.  Or you can call it the Natural Spectrum Hormone Therapy, the fancy medical term.  Urine, known as plasma ultrafiltrate in medical term,  is a by-product of blood filtration, not waste filtration. The urine is clean and disease-free. The morning first pee contains no much stress neurohormones norepinephrine and epinephrine unless you work very hard  in the midnight and have sleeping disorder. It should contain a lot of acetylcholine, dopamine and serotonin precursors. Drink a lot of watermelon juice can improve your urine taste. You can find the fact of Urine Therapy from http://search.msn.com/results.aspx?FORM=SMCRT&q=urine%20therapy 
2. Change your lovemaking and ejaculation principle - make all women achieve orgasms with one and only one ejaculation in the all day-long show. A violent orgasm will exhaust or blacken out your partners with a high level of norepinephrine, epinephrine and prolactin in their bloodstream for the little death, or triggers their Parkinson's body shaking responses with a sharp drop of their brain's dopamine, but no yours. Stimulating the clitoris and G-spot/Epicenter (that is, stimulating their clitoris and blending their cervix and G-spot at the same time) can knock out there cerebral conscious control center and produce this type of violent (Parkinson's or seizure) orgasms (please read What's Sexual Orgasm ). My readers will love to see their real orgasms.  Let their bodies be flooded by prolactin, norepinephrine and epinephrine, and then collapse (http://actionlove.com/extra/girloversex.htm),  but not yours!  In this way, you can preserve your body for your health and make more money too, and of course, drive all your partners to crazy orgasms, the little death. And, you will become a super-sex King Kong conquering all your women.  When you shoot your hot load out, it will look like the 4th of July's fire works.  One stone shoots multiple birds. Note: I have  few,  long-term female customers who experience sexual exhaustion symptoms the same as what men do. Also, Warning: excessive prolactin, norepinephrine and epinephrine in the blood stream will destroy the adrenal, testicular/ovarian function for infertility - semen/sperm production disorders for men and menstrual disorder and excessively colored vaginal discharge for women. Unlike men, when birth control pills fake the menstrual cycle, women won't be aware of the destruction of their pituitary-ovarian function with a chronic, excessive prolactin, norepinephrine and epinephrine (adrenalin) level in their bloodstream.
