> There is a technique which can allow the best of both worlds. An

> very patient and understanding partners.

> The technique involves replenishing the fluids as quickly as they\'re

> First, wash out the rectum with a strong antiseptic. Then insert a
> 6 Fr. (2 mm) hypodermic syringe through the anterior rectal wall into
> the prostate gland. It should be attached to about two feet of sterile
> clear plastic tubing, which should be primed with sterile isotonic
> saline. Wash the penis with a strong antiseptic. Put on a condom.
> Make sure it does *not* have any spermicide or other additives. The
> condom should be filled with sterile isotonic saline as you put it on,
> and should have the other end of the clear plastic tubing running down
> its length on the interior to the reservoir tip. Caution: Make certain
> there are no air bubbles in the condom or the clear plastic tubing.
> Bubbles can cause air embolism, necrosis, and permanent loss of sexual
> function.
>
> When you reach orgasm, the fluids will be pumped back into the prostate
> and endlessly recycled. The orgasm and ejaculation will continue
> indefinitely. The only limit is when you need to urinate, since that
> isn\'t possible during ejaculation. Or when your partner gets bored.
>
> To terminate, simply unplug the plastic tubing at either end. The
> ejaculation will then come to a stop within a few seconds. Try not
> to have a bowel movement for at least six hours after doing this, to
> prevent possible infection of the rectal injection site.
>
> To go on for even longer, some brave sexual pioneers have implanted
> shunts into their bladders, allowing urine to drain through the
> abdominal wall into an external bag. I do not recommend this. The
> body really isn\'t designed for multi-day orgasms. The continually
> elevated blood pressure and heart rate can lead to problems in
> susceptible individuals.
>
> The record orgasm is just over four months. Unfortunately, it was
> terminated by the individual having a stroke. He survived, but is
> permanently paralyzed from the neck down. However, he says it was
> worth it, and he\'d do it again if he could.
>
> Some experimenters say it\'s not just the duration but the intensity
> that\'s important, and the intensity depends on the rate of flow. So
> they\'re working on hooking up pumps in-line. Pumps from old dialysis
> machines, and from discarded heart-lung machines are being tried.
> Perhaps I\'ll be able to report on their success a year from now.
