This is so NOT what
electrostim is all about.
Which is why I am repeatedly telling people on this site, "just because you read about something on the internet, you shouldn't try it at home without research and training." Bondage, flogging or whipping, and electrostim can all be dangerous without the proper training, and can be perfectly safe if one knows what one is doing.
The price of electro stim toys is so high it's hardly surprising some people get to thinking of plugging their partner into the mains.
The Folsom units and specialized attachments are outrageously priced, but other units can be had very reasonably.
I'm pretty open to things, but have never played with electro-stim. What's the idea behind it? Pleasure? Pain?
For some people, pain
is pleasure. The idea behind it is pleasure. Electrostim units are adjustable. The two sensations that are the desired result are tingling and involuntary muscle contraction. If it is done correctly, a dipole electrode in the vagina or anus causes those muscles to contract and relax. It can feel almost like the contractions experienced during orgasm.
It's too bad that half-wits like this guy can scare so many people off from a perfectly fun & safe activity.
