Could be. I can't argue that it's not. All I can say is that the three 
benefits I've seen - the quantitatively and qualitatively enhanced orgasm,
the improved alertness, and the increased stamina - are persistent, and real
for me. If they're psychosomatic, that's fine. I'd go with Crowley here:
belief is not required; you do certain things, you get certain effects.

Thanks for the pointer - I shall check it out.

I thought it was pretty bizarre. That's why I questioned it.

Physical fatigue doesn't cut it. I think most men would agree that
they can get the "roll over and go to sleep" feeling from quite passive
sexual activities, provided they lead to ejaculation. Also, though sex can
be very exertative, even at its wildest it doesn't burn the calories
that squash, skiiing or running do. If it did then there wouldn't be any
such thing as a jogger :-)

Oh, the Taoists don't treat semen as some byproduct; they think it's a treasure
to be hoarded. I am likewise in the dark about the source of semen. I know 
that its mainly prostatic fluid, but just where the prostate gets the 
ingredients I don't have any idea.

Um, I think you mean "sperm is always being replaced". That is true. As for
semen, I'm willing to believe that there's a certain amount of supply and
demand involved.

>(weird analogy example here: does your body stop manufacturing BLOOD simply

The blood analogy is one the Taoists use too. They argue that, just as you
should wait a while (weeks? months?) after donating blood, because it takes 
time to build your supply back up, so males should wait for prolonged periods 
between ejaculations. 

Further to this, as males age they are advised to wait for longer and longer 
periods between ejaculations because they don't produce semen as quickly. So 
while a buck in his late teens can feel free to paint the walls and put out 
small forest fires with the stuff, males past the age of sixty shouldn't 
ejaculate at all. I'm not saying I agree with this - that's just the way it's 
presented in the literature. However it does sound reasonable to me.

Well you sure can't do it double blind ;-)

Right, I'll just toddle along to the nearest lab and settle in, shall I?
Seriously, I'm not trying to convince anyone. I'm just curious about whether
there is a physical basis for what I'm experiencing. If anyone does know of 
formal studies, I'd be interested.

>Have your friends likewise used a "control" in their self-study?           

Only in the sense of 'before and after', and of course they might be undergoing
a placebo effect too.

I grant that raving is exercise, but I did not go to more raves, or 
undergo more of any sort of exercise after beginning to retain than I
did beforehand. If anything, I've exercised less.

Like I said, I avoid drugs. I've sped once at a rave, and that's it. Before
learning to retain I could go four hours on fresh air and mineral water. Now
I can go ten hours on fresh air and mineral water. And feel MUCH better after.

As to nutrition - I eat all kinds of things, but my diet has not changed
significantly over the past year.

Sorry, but there's no lifestyle change to speak of.

I'm entirely skeptical of the explanations offered in the Taoist literature, 
and if I wasn't experiencing a marked effect I wouldn't give the practice any 
credence. As it is, I can't agree that this is a myth.

That's a good explanation, as far as it goes. It doesn't explain why the 
"sleepy" effect becomes more marked with age, but it does give me an idea
about why not ejaculating might prevent that effect. See, you not only don't
get sleepy, but you can maintain your erection as well. That seems to imply
that a non-ejactulatory orgasm is not a "complete" orgasm - that it doesn't
get your professor's parasympathetic nervous system to kick in and spoil
the fun. If that's the case, then to hell with "complete" orgasms - incomplete
ones last much longer and feel much better and .... etc. ad boredom.

I disagree that you should be exhausted by sex, or at least not by the usual
15 minutes to an hour. Are you exhausted by an hour's dancing? An hour's 
skiing? An hour's squash? My present experience of sex is that it is
energizing, that it makes you feel full of get-go and wide-awake. Why SHOULD
it be tiring?
