How do I start feeling new sensations?

I’m pretty new to Aneros, just got the Helix Syn Trident and have been using it for about a month, but I have felt nothing different than a piece of plastic inside me. I have always had trouble getting pleasure from my prostate (something tells me that it’s just impossible due to my genetics or something) and was hoping to turn things around when I bought the Aneros.

I have tried everything, porn consumption, positions, the do-nothing method, different
kegel intensities. I have read every success story and tip regarding prostate play that you can imagine, but whenever I use my own, it just feels like somethings inside me. It’s not really a “foreign” feeling, it’s just something in there that’s not bad- or good-feeling. And I know it’s touching my prostate because when I masturbate normally, it feels much better. Is there any way to make sure that the proper movement is being created on the prostate from my contractions?

I’m not sure what to do now, I want to keep trying but every session has been a dud. Does anyone have any tips to make this experience more like it should? To make at least SOME feelings occur instead of just existing?

Thanks guys
