First Aneros Session Recount

Massager: Aneros Helix Trident
Lube: Coconut Oil (Lubed toy, hole, and used a lube shooter)
So, before I started I read a lot about common techniques and practices. I even watched a couple of videos of people having prostate orgasms and super orgasms (or so they say) with the aneros to have a frame of reference.
Once the toy was in, I laid flat on my back and started to do some deep breathing exercises. After a few minutes of this to get relaxed I remembered that in some of the videos they say that stimulating your nipples can help. So I started with that and rubbing other parts of my body (never touching my penis) and this did feel good, especially with the deep breathing.
After a bit of this I started to do some kegel exercises. I was having a tough time of actually feeling the massager inside me, I didn’t feel pressure or full or really anything. But I tried visualizing the toy inside me and that helped a lot, I got a clear picture of where the toy was and what it was doing.
While doing the kegels I felt what I could only describe as “wisps” of pleasure, like tiny little bursts of a pleasurable feeling I felt move from my prostate area upwards. I tried focusing on that feeling like some guides say, but I couldn’t really hone in on it. I went back to my deep breathing and nipple play and kinda just reset the situation.
Then, instinct just kinda took over, it was much less cerebral. I started moving my hips up and down while doing the kegels, it felt good so I just kinda rolled with it.
I knew I felt something, but I didn’t know what. It didn’t feel like anything I’d experienced in sex or masturbation before. The best way I can describe it is when you see sheets of water going down a window, but the water was small bits of pleasure and the window was my body (from my ass to my head).
At this point I don’t really remember what I did, I was just continuing what I was doing (the kegels, the moving my hips up and down, the nipple play, and the breathing) when suddenly my breathing went shallow and fast, and after a few seconds my torso was having uncontrollable spasms. My breathing got very heavy and fast, and my torso was shaking for about 10 seconds. Then, nothing.
I just remember feeling thirsty, my lips were dry, so I grabbed some water before looking down. The towel under me was dry and my dick was still soft, so I knew I didn’t cum, but I did feel a good amount of pleasure. At this point I wanted to reapply lube (I probably didn’t have to, but I’ve never done ass play before and I don’t want to take any chances of not being lubed enough). This was a natural break point anyway. I checked the clock and it had only been about 20 minutes since I’d started, so I knew I was gonna go back in for more.
After my quick break, I put the toy back in and got ready again. I watched one of the videos again to see what the success stories looked like, and I noticed way more leg shaking than torso shaking, so idk.
Anyway, I went back to what I was doing before, breathing, kegels, nipples, worked my way back in over the next few minutes.
Then, my breathing went shallow and hard again. I could feel myself quickening my hip movement involuntarily. Then my whole torso and legs went into spasms, the waves of pleasure were more intense this time (still not really that strong though, any penile orgasm would be much stronger), but I couldn’t really focus on them at all, I was just experiencing them. My knees eventually bent and were shaking vigorously. This time the shaking went on for about 30-45 seconds (at least so I think, it was much, much longer than the first time). Then, it just stopped all at once.
The upper part of where my quads meet my hips were sore and I just kinda laid there catching my breath. I can only describe what I was in as a trance, I didn’t really have too much conscious control of my body. Again I hadn’t cum or even gotten an erection.
I’m not really sure what happened, not much of the pleasure was deliberate and it wasn’t really comparable to anything I’ve experienced from sex or masturbation. I don’t really know what to make of it, but I did like how relaxing it was and I see that there is definitely potential there.
I’ll probably give it another go sometime this week.
Is there anything I should be doing differently? How do I have more “conscious” pleasure, like something I can definitely feel, not something that’s like in the background?
