Case Study -  On Preamture ejaculation and solutions, precum, nervous function and sexual orgasm
Dear Dr. Lin
I have a problem with premature ejaculation for some time now and I have been trying to solve it for quit some time as well. I went to to a sexuologist as well. I can find all the syptoms I have in a lot of teh articles I read on your site like the over production of pre cum even when just kissing over viewing sexual activities. I can very well imagine tha teh cause is over masturbating. Now in most articles and with the sexuologist the advice I got was doing maturbation excersices to prolong the time before ejaculating so masturbating as long as possible before ejaculating I think these exercises are comenly known as start stop exercices. Know after reading articles on your site I have a great doubt whether this is a good idea or not. Can you please tell me whether is should continue to do this or not and if I should continue how often is a good idea? The sexuologist I went to also told me about the sympathetic nervous reflection and the serotonin level in the brain and how!
anti depressives can help with this. Can you tell me whether the masturbation exercices are a good idea and what other things I can try..

Kind Regards

Dr. Lin: 12/12/2001>
What your sexuologist suggested are:
1. Use the masturbation friction to numb the penis surface sensory nerves (by forming a thin layer of scar tissues like a condom!)
2. Use the first ejaculation to discharge or burn the neurochemicals (particularly dopamine) and DHEA/testosterone and increase the level of orgasm inhibitor prolactin for mitigation of brain's sexual excitement.
3. Use antidepression (antihistamine) drugs or alcohol to sedate the sympathetic reflection.

If you have a lot of precum and your erection is weak, none of them work.

When precum floods your urethra and prostate ducts, your urethral and prostate nerves become hyperactivated by the precum's prostaglandins; Protaglandin E-1 (PGE-1) stimulates the penile/prostate parasympathetic nerves for erection, while PGE-2 acts on the penile/prostate sympathetic nerves for opening the urethra and prostate ducts for ejaculation or seminal emission (leakage). Unfortunately, precum contains more PGE-2 and less PGE-1, so that it will stimulate seminal emission before PGE-1 can balloon the penis to an extreme for blocking the penile/prostate sensory nervous communication. The Masturbation Exercises can numb the skin-deep surface sensory nerves, but not the sensory nerves in the urethral tube. You will end up with a flooding of precum that hyperactivates your prostate sensory nerves. That is, you may ejaculate upon penetration.

The first ejaculation will burn a lot of major brain's neurotransmitters such as acetylcholine, dopamine and serotonin. A low dopamine level kills your brain's sexual excitement and increase your prolactin level in the bloodstream. As a result, you can last longer if you can re-erect your penis for the 2nd round of lovemaking. When I was young before I got married , I used to have 3 rounds of lovemaking in one session for 2 hours. Usually, the 2nd round can last very long (more than 40 minutes), but the erection is weaker due to a low level of acetylcholine in the brain and a weaker penile parasympathetic nervous function, while the first run is with an extremely hot blood and hard erection but comes short. In the 3rd round, the erection is much weaker and lovemaking is cut short and very worn out and exhausted due to the burn-out of all the neurotransmitters and hormones! With this practice for 6 months, I became impotent and experienced sexual exhaustion symptoms and pains all over my body. I had to take herbal medicines plus animal brains to rejuvenate my body. After that, I started my sexual chikong study and discovered how to achieve a 2-hour lovemaking without ejaculation or leaking a drop of semen, and make my wife achieve multiple orgasms. I also have never discharged precum before I decide to come by contracting my PC muscles to stimulate my bulbourethral glands and prostate in initiating the secretion of precum, or by the penile over-erection (over-ballooning) pressure reaching the bulbourethral and prostate glands. I don't have to put on a condom before I reaches that moment. When the precum floods into my urethral and prostate ducts, the sexual sensory nerves produce an overwhelm pleasure in the brain and then a powerful orgasmic contraction in the prostate and seminal vesicles and their adjacent muscles pumps the semen out of my body. My wife usually experience another powerful orgasm with my powerful, hot semen jet when I don't have to use a condom. Now, we don't need conceptractive protection any more and Sex can become more excited after women pass menopause. 
I have studied the effects of precum on premature ejaculation for a long time and concluded that if you can stop your precum, you can solve premature ejaculation. If you use the first ejaculation to prolong sex, you should not have a 2nd ejaculation which may lead to sexual exhaustion with a frequent sex, particularly after age of 25. At your age of 28, you may not afford a frequent 2nd ejaculation. 
Drugs can very effectively sedate the sympathetic nervous functions, but they make you impotent too.
A long-term use of drugs leads to impotence as expected. It does not make sense to prolong sexual encounter with a impotent penis or improper feeling in the brain.
The general solution for premature ejaculation are:
1. Fool the brain and interfere the sympathetic reflection by inducing stress in the low back and tail bone with contraction of the tail bone muscles - anal breathing or chikong breathing during lovemaking, that is, release the muscular stress against your prostate and bulborethral glands and don't contract your PC muscles!!!! ( please read the articles in http://www.actionlove.com/extra/kungfu.htm ).
2. Circulate the sexual energy from the prostate back to the spine and tail bone - synchronization of the inhaling and anal breathing with the sexual thrusting.
3. Balloon the penis without oral or hand sex - the penile ballooning method to produce a high blood pressure that can block the nervous communication in the urethra and prostate.
4. Correct the acetylcholine/parasympathetic and serotonin nervous functions, and block the dopamine-epinephrine conversion in reducing the sympathetic nervous functions.
5. Block the sympathetic alpha receptors to produce a spontaneous erection.
6. Block the acetylcholine re-uptaking to energize the parasympathetic nerves for releasing more 2nd neurotransmitter Nitric Oxide and its metabolized dilator cGMP in the arterial walls to drive erection.
7. Increase the production of relaxation hormone PGE-1 in the penile tissues and arterial walls for prolonging a long erection, and reduce the production of PGE-2.  PGE-1 will relax the entire tissues in the penis and around the prostate and bulbourethral glands and the PC muscles, and result in a persistently spontaneous (autonomous) erection like a teenage boy in the puberty. You will feel full in your pelvic cavity with a hard erection.  It is like your entire-boy blood filled up the penis and pelvic cavity. Our customers have reported that injection of PGE-1 into the penis results in a persistent erection for few days (longer than 8 hours)  and thus damages or fatigues their penile nervous endings. Since a hard erection corrupts the penile veins and cut off the return blood flow, PGE-1 is trapped inside the penis and the erection won't back down even after ejaculating.  My experience of having a full power-up erection (as shown in http://www.actionlove.com/image/power-up.jpg ) is: my penis won't back down 10-30 minutes after ejaculating since too much PGE-1 is still acting on the tissues and the parasympathetic nervous endings. 
8. Eliminate or reduce production of precum. Note that the over-masturbation or/and PC muscular exercises will train the sympathetic nerves in the bulbourethral glands to produce excessive precum!
Our products such as MoodMax, LastLonger, LoveLonger, 5-HTP and GABA are the dietary supplements that alternate the brain functions and cut down the production of precum to prolong sex for young men, in conjunction with the Sexual ChiKong Intercourse and Breathing..
