Prostate buzzing and then nowhere and then interesting feelings when I take it out

So I am new maybe 20-30 sessions. I have the progasm. I am new to all of this and this is my first toy. I have no prostate health issues.

I can get to the part where there is buzzing in my prostate and it feels like you sat on a vibrating cell phone. It doesn’t build on anything there. Hours can pass. Usually at that stage my prostate must be really swollen. It feels like it could crowd out the progasm but it does stay inside of me (maybe not as high but I don’t know). At this point, voluntary contractions are not as comfortable. It seems to take more effort (hard to explain), like maybe there is more drag I don’t know (I used plenty of lubricate so I don’t know). I thought at the buzzing stage you could just relax and it would take over, but that doesn’t seem to be the case.

The interesting part is when I take it out. I don’t know if it’s the tip or the middle part but it drags against something that is much closer to the insertion point. It feels tingly there and like something could develop. I have tried manually holding the progasm on this point but it didn’t seem to take off. The interesting part is that tingly spot is way closer to the entrance then where the progasm pushes. It looks like the contractions of the progasm are suppose to pivot and cause the progasm to nudge the prostate. Then I am guessing when the prostate swells, at some point the voluntaries turn to involuntaries and then the progasm does what it needs to do to get you there. I was wondering if the tip of the progasm, nudges the prostate to swell and then when it is swollen it’s trapped between the tip and the middle of the stem to lock into place. Is that where there is a hump there?

This is my first toy but I looked up other devices. The zcargel looks like it hooks in closer to the opening.

On some self discovery site it said that you could use your finger and if you push on the button then magical things happen. Is this button the same as what is pushed on by the progasm tip (it seems to be hooked in to push on something).

Is there anyone out there that has a larger model like the progasm and feel strange with the swelling? Like it was so swollen that you don’t know how the progasm could move on its own? Anyone out there got to the buzzing prostate stage, and what finally made you climb higher and do you recall what the next stage felt like?

Thanks.
