Case Title:  On the mechanism of Lasting Longer for her multiple sexual orgasms.
Reader: 8/01/2003

I have read a lot on your page about how using the penile ballooning thing can actually numb the penis. I am confused. Maybe numb is not the right word you want to use, but why would any man want to numb his penis? It is still possible to control ejaculation without numbing anything. Why would men want to reduce their pleasure?

Dr. Lin: 8/01/2003> Yes! It does.

The need for lasting longer depends on individual. Some men want the partners to achieve multiple orgasms for the male pride; others just want their own orgasms, but don't care about their partners' orgasm pleasures.
Our Tao of Love is to help a loving couple please each other.
How long you should last during sex? it depends how fast your partner can achieve orgasm.

The natural penile numbness is achieved by a hard erection lasting longer 40-60 minutes.  This is why penile ballooning and anal breathing (butts exercises)/sexual Chikong get involved in lovemaking. 
The fist stage numbness, which is what you need, is due to the penile internal blood (erectile) pressure that compresses the urethral nerves and blocks the urethra-prostate nervous transmission for preventing the ejaculation triggering in the prostate via the L1/L2 circuits.
In the first stage, the glans penis and penile shaft still have a lot of feeling, but only the urethra-prostate nervous transmission is blocked. Generally, the penis entire this stage in about 3-5 minutes after penetrating the vagina. If you can pass this critical transition stage, you can hold your ejaculation back for another 20-30 minutes unless your erection is weak or you use PC muscle flexes to support your erection.
During the first stage numbness, if your can balloon your penis up and bring your erection into the 2nd stage of erection as described in -
Mechanism of the Penile Ballooning for a better sexual orgasm - on the the 2-stage penile erection theory for Penile Enlargement.
Your penile cylinder become a testosterone-DHT conversion chamber and the penis erection is harder enough to almost completely seal the in- and out-flow of the blood circulation. There will be no much fresh blood flowing in. That is no more testosterone and acetylcholine to retain the penile nervous sensitivity. At the same time, there is no enzymes in the penile blood pool to decompose or remove (re-uptake) the superhormone DHT and the arterial dilator cGMP. Thus, the penis remains extremely hard for 1-2 hours until the prostate experiences excessive stress that triggers the L1/L2 sympathetic nerves for ejaculation.
Even if you ejaculate, your penile erection won't back down for another 10 minutes after you hold an erection for 1-2 hours. 

If your prostate won't experience stress, you won't ejaculate. This prostate stress occurs due to an excessive dopamine-adrenalin conversion in the adrenal medulla and the brain, where excessive adrenalin will trigger sympathetic Fight or Flight (Fight = Ejaculation; Flight = Erection Withdrawal during asexual activity).
If the dopamine-adrenalin conversion is fully blocked by the Serotonin and GABA nervous system, your erection will never back down. Of course, your penis is fully numbed. If you hold the hard erection longer than 3 hours continuously, your penile spongy tissues (cells) and nerves will be starved to die due to a dificiency of oxygen, hormones and nutrients. This is called priapism -
