How do I know if the p-tip is in its right place?

I feel like the p-tip of my aneros helix sync isn't in its right place. I think it needs to be closer to the penis and I can't really adjust it that way. Its supposed to put pressure on the prostate from the outside, right? I dont think it hits that spot at all. Sadly I am one of those guys who can't even achieve p-waves, yet. But I'm not giving up, just trying to make sure that all the boxes are checked for it to even work physically.
