Sleeping with the Helix got me results!

After unsuccessful attempts with the Aneros Helix I decided to try keeping it in over night in the hopes of it triggering and waking me up. It didn't do that but i barely remembered I put it in till I felt a tingling, so I worked on my breAthing and felt it start to build. I finally got my first male orgasm, even if it was brief!

Im new, and I feel like I might be doing it wrong?

Im temporarily using soap (Or nothing) as lube, and I feel a slight discomfort with inserting and that is all. Once in I feel nothing bad, but Im also not feeling anything that would be on my prostate? I can manually stimulate my prostate by using my hand to move the Helix, but I cant with my anus muscles. Which brings me to the main question.

How should I be using the Helix? Should I clench my anus or use the muscles that would stop me from peeing mid stream (they also affect my anus muscles but in a different way). Is the lack of lube why Im not feeling anything?

Also, I know lube is important, I havent gotten any yet unfortunately.
