Ok that may very well be the hottest picture I've seen you post lol. And now I really want to try making something like that. And now that I'm kinda starting to see a woman with workshop space and skills… probably not a good first project in a while, but definitely something I want to do now that I know it's a thing.

And yeah for estim, especially if you're looking for it to really hurt my advice is to get a decent power violet wand and a body contact cable. Smaller points of contact hurt more, so you can get something like a wartenberg wheel to really do a number. Importantly the pain comes from being close but not touching, it's a very different sensation with touching (which I also love, but that's more TENS unit territory, violet wands and bccs aren't great for it). A narrow gage wire held properly just off the skin can even brand it, but it takes some doing and I'm more a fan of hot or cold branding if you're headed in that direction, less slow precision.

Also cattle prods are fun but not as strong as you'd think, stun guns (the melee kind, not ranged tasers) can be fun but I don't have experience with them, and I've known people who really enjoy shock collars, but they're not as safe as the rest of estim (I've just never gotten around to getting one). I also have known a woman who's brought an actual taser into the bedroom but she was definitely more of an edge player than most.

And yeah if you've ever got estim questions feel free to ask, I've been doing it for nearly a decade.
