Did I just Super-O?

This was my second time using the aneros and I'm unsure wether or not it was a full on super-o, let me describe the feelings I had with it:

First off, I was in my bed listening to this, a hands free orgasm hypnosis wearing headphones. The first maybe 5 minutes I feel pretty much nothing but after that my sphincter muscle started contracting which felt nice, this intensified for a bit followed by a sense of drifting away and then rocking back and forth.

After a while my muscles start tensing up, like all over my body, my stomach, chest, neck, hell even my face was tense, I almost couldn't move my arms but it still felt soooo good, almost overwhelming. At this point I was spazzing a bit in the bed. I was breathing so fast and heavy and by this point the hypnosis audio was just background noise.

But then it didn't develop much further, it still felt amazing and I kept breathing heavily and the tenseness was still there only slowly declining.

Afterwards I just laid there, kind of exhausted but not "satisfied" as I'm used to with traditional orgasms and actually still a bit horny. During all this I never got hard and I didn't cum, nor pre-cum.

I'm wondering if I had my first full on Super-O or if there's even more to it, what do you think?
