Question: I think I am getting there but....

I've had about ten sessions with my Helix and even though I have yet to experience the super O i am still quite enjoying it.

The one thing I've noticed is that I only feel waves/shaking/spasms while breathing in and when holding my breath. When I breath out and as I relax the sphincter muscle i lose the waves/feelings .

For those of you who have had an anal orgasm is this what your experience as well?

I am wondering it maybe I haven't closed the "loop" properly; perhaps I haven't found/hit the sweet spot?

(Note: I am following many of the tips found here including the breathing techniques, trying to totally relax and gently contracting to about 50% of maximum. The sensations seem to be intesifying somewhat.)
