I layed on my back in my bed after lunch. As usual my aless "session" starts immediately (butt buzz). Something new happened today; I felt some kind of pressure that I would have to spread my legs more open. It felt as if a new inner / outer sphincter had been found in the right groin.The sphincter nerves really woke up.
I surprisedly found that I had moved to the stage where all the sphincters run at a fast speed at the same time. Usually rolling takes place 3 times in a row for me, but this time it continued
with the prostate p-waves like the woken sphinceter started to massage my prostate. It felt like my body’s wide p-wave roll was running back and forth over my body from the shoulders to the soles of the feet. Vagus signals, of course, traveled along my body to the brain. It felt like this would never end, I had to interrupt my enjoyment. Quite an experience, whether it could be due to that awakening of the sphincter?
Sounds like you’re making good progress and discoveries. This isn’t exactly what you’re talking about, but I’ve found that in addition to the two anal sphincters, I’m able to constrict my rectum around a Helix, not dissimilar to taking a dump, but also sort of pulling up at the same time. The perception of the rectum constricting, may be contributed to other muscles in my pelvic area. The combination of these 3 muscle groups working together pressing on my prostate would trigger super-os. This may be a heretical approach, being aggressive, because I’m not at all relaxed doing this, but it works.
