First HFDO?

Hello friends, here I am again. Today I am trying to understand what I’ve felt on my last session (a few hours ago).

First of all, I know that everyone has different experiences with this and nomenclature is just a way to simplify concepts that we are trying to communicate. But I really want to understand what I felt tonight, so I will try to explain.

Recently I started to felt and recognize the p-waves, feeling that pleasure and accepting that my prostate awoke and I started to rewire. Tonight I tried my vibrating prostate massager (it’s like a vice 2) in another position: with my legs more elevated than my body and watching porn. In a certain moment I started to feel some really good vibrations. I decided to (try) not pursue the feeling and continued to enjoy the moment. A few minutes later the sensations started to get really strong and good, and I closed my eyes, not focusing my attention on the porn anymore, to enjoy these sensations.

Then, I (think) felt an orgasm coming up. I remember that I was doing really strong kegels and contractions, holding up really strong and for as much time as I got. In a specific moment, I thought I was ready to orgasm. The feeling was very similar to a penile orgasm, but missing the sensation of ejaculating on the end. I had a few involuntary contractions, like when you have a penile orgasm and the dick moves up alone. When this passed, I was like “no, please, it was too good, come back”. It was like being on the edge of an abyss, just needing to make a leap of faith… and then going back. It felt incomplete, waiting for the feeling of ejaculating and this feeling never arriving.

After that I felt this one more time (but much weaker) and I took off the vibrating prostate massager, got in the bed and stayed there for a while. I noted that, in these moments in the bed, I was trembling and could felt some really good and strong p-waves. Even now, some hours later, I can still concentrate and flex my muscles (like kegels) to feel little p-waves (or what I think that is a p-wave because it’s a little pleasured).
For those who could ask: I had a hard-on on all the moments that I felt the orgasming feeling and the strongest p-waves. I leaked pre-cum on those moments, but just a few beads.

So, after all this explanation, these are my question: was that a HFDO? Am I on the right way of rewiring and experiencing it? May I contract less? Or more? What are your experiences with this or how was when you first have something like this?
