Skating on the rim of the abyss

Sounds like it to me!

Are there other things around the corner?

You betcha, @theplaything! There are lots of other things around the corner. Just relax, enjoy, and open yourself to them! 🙂

...things started to get very intense. Whole body uncontrollably shaking and writhing, getting out of breath, wave after wave of euphoria crashing over me... This lasted for about 20mins or so. ... I felt like it could go on forever!Have you ever had a traditional ejaculatory orgasm produce the same effects? If you go read the definition of a Super-O in the Aneros WIKI, you'll see your description almost exactly coincides with aspects of that definition.
Is this what some of you class as a Super-O?I would certainly designate such an experience as a Super-O so...
Congratulations to you for having arrived !
Good Vibes to You !

With a traditional ejaculatory orgasm I'm more focused on the feelings in my cock. This super-O thing felt like a more holistic thing. Almost as if some kind of energy shot up my spine from my bum and exploded in my head and then spread to my fingers and toes. Like a Doctor Who regeneration scene.

I think I've experienced this a few times before except this time I was more aware of what was going on instead of trying see what was around the corner. More alive in the moment.

Any advice on having longer sessions?
