I purchased the MGX Syn Trident, my first Aneros, while on vacation last week. Yesterday was the first attempt, and as expected, not much…. There was some warmth radiating down there at one point, but mostly just felt like something inserted. I haven’t completely mastered and isolated the muscle groups but alternated between clamping and pushing at various strengths and lengths of time, trying to get into a “rolling” wave of motion. I can feel the Aneros moving in and out but not really a rocking pivot about a fulcrum. I know that I need to try different positions and really focus and relax, but obviously it sounds like my first experience was normal. So I’ll be lurking, practicing, maybe asking more questions, and hopefully rejoicing soon enough. That said, I was pretty confused by the different models and descriptions Is it as simple as they’re just slightly different in shapes to accommodate differences in human bodies? Thanks in advance.
