Masking some progress....I think

So I took the time tonight to put in the Helix and see if I could progress any further towards a Super O and get any new sensations. Nothing really new for a while. After a while, I think I did notice slight sensations, 1 or 2 may have been slightly pleasurable. At one point I thought I felt a warm sensation near my scrotum, but I could have been mistaken. Also, I would randomly get strong erections and at one point could feel it pulsing for about a minute. My belly also seemed to be pulsing. After about an hour, I switched to the Progasm. Nothing really interesting happened, but at some point I did start to leak precum. Not heavily, just a little bit. All the while I was switching positions, watching some erotic videos, and doing contractions. I've been using Aneros for about 6 months non-regularly. Nothing ground-breaking, and just a new sensation or two. I can feel it going out and in if I breathe through my stomach expanding. That did bring on some interesting sensations. I eventually ended with a regular penile orgasm, which didn't take long, I was already really sensitive.

My question is, does it sound like i'm making good progress? This was the first time I took it seriously and took the time to listen to my body.

The only thing I'm not sure about are the involuntaries. If I suck in and push out at the same time, I can trigger spasms (they feel like they're in my pelvic wall) and my penis will spasm out with it. But they don't feel pleasurable at all, just twitching. Is this an involuntary?

Last statement before I post. I can also suck in my anus really deep and this brings on spasms and a very light numb (yet almost pleasurable) sensation. This is with or without the aneros toy. What could this be?
