Frustration?

I've had my aneros products for quite some time now, 3 models actually. Sgx classic, Eupho and helix. I have had dud sessions for quite some time now and my guess is still trying to find that right model to fit my needs. I don't think the tab on the helix hits the sweet spot and I don't think Im ready for the eupho. Maybe I'm using the wrong lube. I guess I'm just frustrated cause I don't use it that often and even after about a year of using it I still consider myself a noobie but have just had bad luck. I've only had 1 good session where I've had 2 dry orgasms but nothing else. Could I be using the wrong lube? I bough some glycerin free to ease the after effects and thats water based. I guess any feed back would be great cause Im still wanting my super O. I think Im going to get a Progasm.
