I just had a really long session with my Helix Syn using great tips and lessons from this subreddit and Mindgasm (respectively), and while it was good to practice separating out the PC vs. sphincter, I wasn’t getting anything like an involuntary spasm. After a long while, I started doing random contractions, trying out different positions, etc.
I decided to just give up and jack off to finish. Maybe it was either getting hard or just relaxing after that decision, but I suddenly felt like I was about to have a wet cum. For a few mins I was left in a state where my PC muscles were contracting as if I was dry cumming and it felt amazing, like I was on the brink of ejaculation from edging. I tried keeping this up but eventually it passed the point of no return and I ejaculated.
While I’ve read about all the things (title) and super O’s, I’m not sure what I just experienced. Was it just involuntary contractions, or one of the other things mentioned in this sub?

Sounds like a HFWO. What happens is when you got hard and close to ejaculating from jerking, your prostate swells and gets much more sensitive so your Helix took you over the edge. It’s not clear in your post but I assume you stopped jerking when you felt you were close.
