How to start

I have a helix and I've been trying to figure out how to get started with it alone. I've used it a couple of times with masturbation, once with oral sex. I definitely felt prostate stimulation and all sorts of movement once things started going, but when I try alone I'm not entirely sure how to do anything besides tense the muscles down there, or even if I'm supposed to be doing that or something else. I've read all the instructions and a lot of the forum posts, but I'm just really not sure if I am even going in the right direction, I don't even really know how to use the muscles properly, is it like wiggling your ears or is it something that you can learn?
