Sign that aneros won't work?

It's possible but I don't think that's very likely. I think any male can learn to have a prostate orgasm. What's a typical session like for you? When you felt what you believe was the onset of a prostate orgasm, did you stop what you were doing? I've found that my natural instinct is to stop near the onset because it can be a little scary and uncomfortable. The dull, deep sensation also feels a bit like fatigue to me so I have to push through that.

jja2 — I'm sorry to hear of what you describe and no it is not a sign that the device is ineffective. The energy that supports the construction of orgasm is first and foremost manufactured in the mind. For some of us, we don't need auxiliary tools to produce such organic pleasure, but of course, it can't hurt! I'm sure you're probably sick of reading about: "stay with it, don't give up, etc, etc," And, all that is true. Are you able to find a suitable place free of external input, a place of tranquility whereby you are at complete peace. I encourage you to pursue your course but make some mind-shifts that just may be the key you are searching for in order to release the hovering and spiritual energy necessary to attain the glorious freedom housed within us men.
