I'm just starting to learn about HFO and have not put much effort into training myself. I have started experimenting with contracting my pelvic floor muscles and can get to a point where each contraction sends a shiver up my spine. It starts off as a small shiver, but if I keep contracting in rapid succession it builds to a stronger shiver that eventually makes my neck muscles tense. Is this a mini orgasm? Is this the right path to pursue to achieve HFO?
