Has anyone ever tried something like this?

I have not, the most electric thing I have had in there is a rabbit. Which was very nice.
Estim is an odd one, not sure I could get down with pulsing shocks inside my ass. Voltage is very important and I don't know what kind of gates they put on that dial to keep to keep it safe. The difference between pain and pleasure from electrical activity is very minor.
Now this I could get down on : )
we tried the estim cock cage too and it was a big nope. Too shocking even on the lowest setting but maybe we bought a cheap version.
I have subjected myself to a dog collar shocker before. Not in a sexual context, just bored as a high school kid long ago. It was set for a 60# dog and was not too bad. The collar was on my arm not my neck or genitals, so there is that. It did make me feel like I don't need to explore it as a kink, electricity is just so potentially dangerous on the wrong settings.
Personally I would also be scared of an aggravated Vasovagal attack, which causes some to black out.
