An popular estim device consists of two soft rings made of a conductive silicone and a controller that provides a small amount of current to the rings. Typically two rings are needed with the current flowing from one ring pf the rings to the other. Often the rings have a slide or tightener on them. Slide one ring onto the penis loosely then cinch it tight using the slider at the base of the penis. The second ring slides on to the penis as well but near the tip maybe even on the glans area, but maybe just back of the glans (instructions for circumcised guys).
A popular and inexpensive controller is one that has a variety of different electrical pulse patterns and a continuous knob that allows you to fine tune the amount of the electrical pulse from the estim. This is powered by two AAA batteries so we are not talking a lot of current-- we are talking a light tingle to something that you mint find a bit uncomfortable and all the settings in between.
These devices are terrific fun, and only get more fun as a guy gets older and gradually lose speed with regard to getting hard. If you have never tried one of this this is something no adult male should ever miss out on. With a well functioning estim device you will be climbing the walls almost with the first pulse of electricity. Kick back and enjoy the fun of being focused on what is happening to you as you attempt to adjust the sequence of pulses and varied current.
I have had the same estim device and have been enjoying myself regularly for several years. But suddenly the current to the rings stopped. Was it in the rings or the machine? The little butt plug that also came with the device connected to the same machine was working fine so there must be a problem whereby the silicone rings were no longer connecting.
I searched ebay and found another machine except that the rings were of a fixed diameter and larger than I thought they needed to be. Last night I decided to open the package and try it out. I started trying to do the exact same thing I had done with my older rings by putting them at the glans and base but they were way too big. I soon discovered that I could put the biggest ring over my scrotum and slip the smallest ring loosely over my penis.
Wow! You talk about grabbing my attention. These rings being bigger make much better contact with my skin even though they fit looser. This is way more powerful than what I was getting from the rings on my old machine. Instantly I am transported to a marvelous place I have never before visited.
WOW!
I got to thinking I might be able to slip a tight swim brief and turn the machine on with the swim brief helping hold the rings in place next to my skin.
I still wanted to get my old machine working with a new set of the thinner rings that cinch up. This morning I found a new set of rings on ebay and I ordered them. I am hoping to repair my old machine as well
The machine I have been messing with has four rings that operate and adjust from the same controller. As my readers know I have never been into partner sex. However, the wiring is set up so that each of two guys could be wired to one controller and this if there were two different guys hooked to the same controller, one guy could be at the controller experiencing somethin first hand but also watching exactly how the other guy's body responds to the exact same setting. Put nice tight swim briefs over the rings for both guys and watch each other squirm as the electrical pulses hit each of them inside the slick-and-tight briefs.
For straight guys with female partners there are two outputs on the controller and the second output could go to something completely different that puts out an electric pulse to the female's pleasure.
These little controllers are very popular.
