Uncontrollable body spasm question???

I have been using my helix for a while now after switching to it from a mgx which was my first purchase. For a long while i didnt really get much from either (about 2 years off and on). I recently bought some new silicone lube cause any water based stuff i use i never felt much. And latley i have been able to really take some time for myself i have been able to make my body go crazy. Problem is i can sorta control it but i dont really feel any kind of amazing pleasure at this point in time. I am wondering if this is normal? I am patiently waiting and mostly just wondering if i am getting closer to bliss? I know its different with every individual but i figured there is enough people out there that someone could explain it better for me..... I just want to say thanks for all the great info on this site it has made it easier to take this journey.....
