What orgasm did I experience?

I’m still fairly new to prostate play, but I’ve got a decent system going on where I’ll practice prostate play with a Helix Syn Trident for about 2 hours, then spend a third hour practicing penile dry orgasms with the Aneros still in. Today, I’ve experienced something completely new to me while masturbating in the third hour, and I’m not familiar with what orgasms are called what, so help me out.

This happens after a significant amount of buildup stimulating my penis and prostate, while I alternate between squatting and standing up (this alternation is very effective at encouraging my regular dry orgasms).

Perhaps unsurprisingly, the feeling was not dissimilar to getting a head rush after standing up quickly, except this rush was felt all over my body, and there was a strong buzzing. I struggled to balance myself, as I was standing up, too. It was, of course, intensely pleasurable, and I was satisfied after, albeit unsure of what I just felt. This orgasm started and ended in about 7 seconds.
