Achieved prostate orgasm amazing.... can this be done with the silicon Estim prostate massager?... a

Hi I have managed to achieve the prostate orgasm (eventually) and the feeling was amazing...but it took me 2 hours to get there with a manual vibrator and felt out of this world honestly...

But I've also bought a double pole 4 pin silicone electrastim prostate massager and tried it with a tens unit

...any advice on how to achieve prostate orgasm with this without frying my prostate!!!!

It feels good but atm don't seem to hit the right frequency etc

I also have some silicone cock rings too I could incorporate with it and a tens lead splitter... in fact I have 3 tens units too lol... 2 are the NHS medfit ones quite powerful PP9 battery!!!

Not sure which way to go with this
