No luck and a bit confused, could someone help?

I started using a prostate massager a couple months back, and I haven’t really felt much so far. I’ve felt the p-wave once, but it was short-lived and I haven’t been able to have it since (I’m not sure what I did that time that was different), and involuntary twitch is something that I think I only experience with my pelvic muscle, which doesn’t really move the massager, and is kinda distracting from feeling the prostate.

Also, I’m getting confused on what I should be doing during a session. I’ve read several posts on this subreddit and other sites; some say to just focus on the feeling and nothing else, some say I should fantasize or watch porn (which would distract from the “focus on the feeling”), and holding contraction hasn’t really lead to any quivering or spasm that may lead to the massager vibrating.

What should be going through my mind, and how should I move which muscles?
