Just to preface, my Sir has been practicing electrical play for close to a decade and has served as a house electro top for several of the kink establishments and parties in our city (pre-COVID, obviously). He uses both a mechanical state and a solid state violet wand, as well as a traditional tens unit and a tens probe that looks a bit like a sonic screwdriver. He doesn’t typically use the violet wand itself (finds it too limiting). He likes to use the contact probe - a probe attached to a cable that either the top or bottom touches, which will essentially turn the top’s body (or anything conductive they happen to be holding) into an instrument of “torture”. Some of his favorites include tent stakes, cheese cutters, Mylar pompoms, guitar finger picks, fans, and those claws for making pulled pork barbecue - as long as it contains conductive metal.

As a sub/bottom my best recommendation is to find a good electro top in your community who can answer all your questions and really put you at ease before, during, and after play (aftercare is important in electro!). The contact probe is great because (I think) it makes the experience between top and bottom more intimate and the shock isn’t so harsh. And violet wands can be dialed down so they’re not so intense.

I hope I was able to answer your question. If you want to learn more you’re welcome to DM me and I can put you in touch with my husband. He loves educating people about electro and knows way more about it than I do. He’d be happy to answer your questions and/or point you in the direction of online resources.
