Estim : pleasure or pain

I have recently tried Estim! I placed 1 pad near the base of my penis and the other just south of the corona! I then SLOWLY increased the charge. I bought a medium priced unit which has 6 different modes.

At the first few levels I could barely feel the charge..... as I increased the charge... I enjoyed every increase. As I reached the upper limit... the feeling began to feel painful! I would lower... then increase... until it was too painful!

I have added a ribbed urethral probe a few times!

I vacillate between the pleasure and painful sensations.

I have orgasmed twice from the combinations of sensations!

Any thoughts?

Keep experimenting, what feels good today may not feel good tomorrow. So many variables. Good luck.

I bought a cheap e-stim device (https://www.amazon.com/PROSPERA-PL029-ELECTRONIC-PULSE-MASSAGER/dp/B07DD7Y9RF) I have been playing with it for a couple years and can't get close to an orgasm. I made a steel anal probe and it did not seem to add anything to the experience. It feels pleasurable at anything but the highest settings. I watch the videos of e-stim orgasms and wish I could get the same results.
