This is basically the unit I have.
E-stim has MANY MANY variations. From a simple unit like this, to straps you can put around his cock and balls, to violet wands, to systems hooked up to car batteries!
I will talk about my unit since that is what I am most familiar with. Also I have played with a violet wand a little so I will get into that near the end.
My unit is very basic. Not only is it used for sexual play, it is basically the same thing hospitals use for pain control. TENS Units are basically the same and I know people who have bought these for that purpose exclusively. A few have discovered the “perk” of other uses for it.
I have used this mainly on my breasts. I was trying to lactate and this was supposed to take the place of pumping, not all the time, though. Before that, though, i was experimenting with it.
You can adjust the strength of the shock as well as how the shock is delivered – single continuous shock, pulsing, pulsing from one set of pads to the other, tingling, etc. you MUST have all the pads attached to your skin for it to work. Mine came with a bottle of special electronic applicator which helps the pads stay on and conduct better. You can put it on your skin or on the pads. Some units come with 8 pads or more.
On my breasts, I put two pads on each side of the nipple. This was one I liked the most. You can also put two on one breast and two on the other. It definitely peaks the nipples and makes your boobs swell.
Some people use it near their vagina as well. I was pretty natural hair down there, so i was unable to do so. I did put them on my upper thighs, as close as I could get, and had some nice stimulation, though no orgasm. You can also put them on his cock, much like I did on his arm. He said he would do it sometime. He was amazed by the spasms on his arm, and couldn,t imagine his cock doing that.
There are limitless possibilities with these, but be careful…. only ramp up as much as you can handle. EStim COULD potentially hurt your heart – and DO NOT USE if you have medical implants!

Violet wands are one of those medical devices too that made the jump to sex play. I am not going to get into whether it works as a medical device.
Basically violet wands are used in stimulation play, just like all the e-stim. It basically deals with static electricity. Imagine feeling static electricity playing on your nipples?
I used one once (while clothed) at a convention. It really did make the hair on my arms stand up. I brought it near my breasts and could feel the tingling through my shirt and bra.
It is one item I would like to add to my collection. They are fragile though.
DO NOT USE AROUND YOUR EYES – you are basically using ultra-violet light
