What is this feeling?

So for starters, I use the do nothing method in which I try to let my mind wander (not focus on an orgasm) but do not restrict anything my body wants to naturally do. I guess I just let my body take the lead and surrender my conscious mind to it.

Anyway, I have had minimal success for how long I have been doing this but am getting better nonetheless. Once in a blue moon I will get really intense pleasurable feelings throughout my body. My entire body feels like it is weightless and I tingle all over, like an a pleasurable electrifying tingling. My brain in completely clouded and I get a light show in my eyes like I’m traveling through space at Mach 20. It is extremely pleasurable and lasts for around 30-60 seconds I would guess.

While it is pleasurable and satisfying, I feel like it’s only the tip of the iceberg on the pleasure scale. I do not feel like this is a super-o but without anything to compare it to, I guess I’m not certain.

Does anyone else experience this and if so, does it get more intense or is this the pinnacle of pleasure?
