I use an old toy railway 12v transformer and some good old stranded copper wire. Looping the wire tightly round the head and frenulum and then experimenting with the other wire (sorry about the "terminology" no pun intended - I've never been an electrician). The urethra and the perenium are very sensitive and tingle wonderfully with about 6v going through them. Bound scrotum at the base of the penis with a urethral insertion is exquisite. Orgasm with this tingling sensation is mind blowing!Be carefully though, if you get the wires too close together you can get Burns also if going up the pipe you may bleed - I know. I don't electro very often but when I do it's indescribable. Happy volting!

Don't think I'd use anything that plugs into the wall.
Batteries only. Also, there are prepared "programs" which vary the feeling, speed and intensity.

Seems like a good episode for a "1000 ways to die"

It's quite different and very hot.
Just don't think you'll cum like that the first time you use it. You need to work up to it and learn what feels best for you.
The best feeling is when you go without cumming for 4-5 days and then use the estim unit.
MMMMMMMMMMM

bump, I want more opinions, please

bump, I need more info

bump again

Looked intense!

Check out the info at http://shop.erostek.com/pages/New-to-E%252dStim%3F.html I have no connection with these folks, but their info page has some good tips if you're just getting started.

I have an old (198 unit I bought from SandMutopia. It doesn't have much in the way of waveform control, no programmability, and the electrodes it came with were just two pennies soldered onto a piece of zip cord. Primitive, but it worked (and still does). Saving up (damn, so many demands on the money!) for something like ErosTek's ET312.

getting back into e-stim after taking a break for a while... feels so damn nice...

I need to get back into it too.

I find this VERY exciting!

Anyone else tried electro stimulation?

Accidently came across this subject on the internet one time.Dragged out a Tens unit that the wife had for her back and tried it. OMG, WoW Incredible hands free cum. Great for watching porn while the pulses stimulate your cock for as long as you can stand it. A couple times I couldn't wait and finished by hand. Unbelievably awsome orgasms.

it sounds awesome !
