Never tried it with electrical stimulation, I’ve seen videos of urethra sounding massagers they look great. On x v I d e o s
I tried it as sounder/recipient. I'll say this, caution and being totally sober are key to enjoying it. I'm in favor of trying it again, but after a negative experience (see caution & sobriety) my wife says no.
The more I try it the better she gets at teasing me. It gives prostate massage a new name, its amazing, I did make my own device that is flexible and very smooth.
There are a lot of sexual practices I don't want to do, but I can kinda 'get' why someone would. This is not one of those things.
