Is this part of rewiring?

I think this is actually a fundamental and normal part of orgasm itself, which is why the Aneros "works." But in your rewiring, you're now much more aware of it.

I think some guys are more aware of it from an earlier age, and learn their intuitive longevity during sex from that awareness. And notably, women's assholes pulse wildly during orgasm too. It's the lowest common denominator of coming.

Hello The_Bishop, 🙂

I agree. I discovered this when having super-T's with my Progasm. Relaxing my anal muscles during ejacugasm cause them to pulse all on their own causing the Progasm to move in and out of me quite a bit. So yes, I'd say it is a normal part of ejaculatory orgasm that the anal muscles spasm or contract and release.
