Hey Spartan,
Ya I experienced the same thing when I started KSMO. Jack told me to let my body do what it wanted to while remaining relaxed and continuing to breathe. I've noticed as well in KSMO sessions, much later, that I would feel like I wanted to move or rock my pelvis. Not saying this is what will happen with you but I would say to allow you body to do what it wants to do and what feels good.
And trust me, you will get to the point as I recently have where KSMO orgasms will be better than the ejaculatory ones. WAY BETTER!
