felt like prostate had a heart beat

I have, but I would call it a pulse, didn't feel pleasure from it though

Good progress jja2 🙂

I have had it only very recently and does feel great. Doesn't produce pleasure itself (other than it feels really cool to have this) but if I do the "roll" that @spinx said, I can sorta get the prostate heart beat to do the roll for me. It's kinda like the beat tickles the prostate even more.

Never felt a tickle though

I don't think you would feel the tickle just from the heartbeat.
I was doing the small contractions which make the Helix move over a small area inside me, and that's what gives me the tickle. The tickle then keeps going if I also have the heartbeat, so I don't have to do PC muscle contractions that much or at all.

@="jja2"It would beat like 4 or 5 times, then stop for a minute, and do it again. Some were a little stronger, while others I could barely feel.
This has been happening to me for some time. If I am semi asleep it keeps going for a while. At the moment I can only trigger it when fully breathed out. It has taken 4 years to get this far!

@jja2 Recently I have been experiencing an amplified pulse in my prostate and genital regions as a regular part of my rides and my a-less; but it is a steady pulse and not the intermittent one that you describe here. It is often accompanied by amplified pulse in other areas, such as the inside of the legs, the stomach, the chest, the head, etc.; and by tingly pleasurable feelings. It's very powerful and somehow very relaxing to yield myself to the rhythm of the experience.
