Vibrating Prostate Massager VS. e-stim Butt Plug

I've had a prostate massager used on me, but I'm anxious to try an e-stim butt plug. I've seen some porn where both were used at the same time. If you've had the opportunity to use both toys, which one is your preference? Why?

Never tried an e-stim… up for it and would love to try soon. Prostrate massagers all day long. The thumping in the spot and fucking at the same time is insane.

I have tried both, neither produced an orgasm but were pleasurable. The prostate massager slid in and stayed in place as did the estim anal probe. Would love to get to HFO that way
