I wanted to share this with you cause I thought it might be helpful for some people.
So I was having a session with my helix, doing alright but not quite great. I got up to get some more lube from the bathroom, applied some more and headed back to the bed. I lifted up my left knee onto the bed just froze because the helix was in the perfect position.
I proceeded to have a wonderful super-o with my left knee up and my upper body lying down on the bed. I think it was because it gave the p-tab better access to my perineum and the helix had great freedom of motion overall.
Try it out some time, it was great for me.
