Not getting the most out of my progasm

Hi lovely folks of reddit,

Roughly a couple weeks ago, I bought the Aneros Progasm. This is my first prostate massager and I am having a hard time getting it working effectively. I have used it pretty much everyday, for a duration ranging from 15mn to an hour and a half.

While it does feel nice, I feel like it is not always hitting the right spot, nor is it stimulating it “hard enough”. I have tried various positions and upon contracting the muscles, none feel as good as when I just slightly moving it by hand or just even walkikg around with it.

Am I doing something wrong ? Any tips on how to get that intense pleasure hands free ?
