Spirex electro stimulation

For some reason I have a recollection of reading an article in the late 1970s which was the first time I'd come across any mention of electro stimulation. I remember the name of the product as Spirex something or other & a description which stated that "one electrode was placed high in the rectum" while "another much smaller one was inserted into the subject's urethra" The article also went on to mention something called an "Ingolstadt Closet" which sounded like some feindishly equipped white room with all sorts of enema equipment. Nearly 50 years later that's all I can remember except that it turned me on so much as a teenager that I must have damn near electrocuted myself several times! I can find no mention of either item in online searches except that Ingolstadt is near Munich! These things sound familiar to anyone?

@alan20cm - Sorry I can't add anything enlightening in response to your specific questions. There are, however, a bazillion e-stim appliances on the market today specifically designed for sexual stimulation. Personally, I use a TENS 7000 which is reasonably priced, available on Amazon (among many other places), and for which there are a large number of accessories available. The combination of a urethral sound and anal plug produces a very stimulating sensation which, when controlled by the power pack, can produce any sensation from a mild/almost imperceptible tingling sensation to a pulsing much akin to being pegged by a reasonably well sized dildo....combined with the sensations produced along the shaft of your penis. If you're already into e-stim, etc you probably know all about this. If not, there is lots of info here on Zity or PM me and I'll be glad to pass along some helpful information.

Thanks duhwizzard - In later years I have tried much more modern e-stim but not completely satisfied with the results which produced more of an irritating prickling sensation than the smooth pulsing contractions I was hoping for. Maybe I didn't buy the best equipment but at a few hundred pounds for the control unit & add-on electrodes it wasn't a cheap experiment. This old 70s stuff really caught my imagination at the time though when I guess very few folks had heard of electro stimulation much less tried it. Problem was the article was short on illustrations or specifications. At the time I made up a bi-polar rectum electrode from 3/4" dia stainless steel rod, two bullet shaped sections separated by 1/4" of insulating material machined to the same profile. Also a urethral electrode from 1/4" dia bronze with a well rounded tip. Problem was a power source. I tried everything from 12v transformers to an old hand cranked 50v telephone generator. Did I give myself wonderful orgasms? No. Did I make myself yelp & leap off the bed? Yep 😃

I do this all the time, using a stainless urethral probe and a custom anal probe/enema nozzle. The power box is a Relax-A Sizer that I modified to raise the oscillation frequency to 30 HZ, and the sensations are almost identical to an ejaculatory pulsing contraction. I can keep myself on the edge of an orgasm for ten to fifteen minutes, and the following orgasm is one of the most intense I've had.
