I’ve been using my Progasm for a while, but I think I’m stuck. Advice?

I have a Progasm and I generally use it with silicone lube, applied both on the toy and rectally via a lube-launcher.

In all my sessions, I can feel the slight pressure from the Aneros on my prostate, but it is often subtle and hard to detect. Very strong kegel exercises can make the sensation a bit stronger, but that’s it.

I have decent control of my pelvic floor, and can generate twitches in my PC muscle easily enough; it doesn’t seem to work very well, though. I’m also familiar with diaphragmatic breathing from my vocalist training, but it doesn’t seem to produce much of a good response either (alone or in combination with my PC muscles.

I have the distinct feeling that I’m missing something.

I’ve read over the wiki without much insight. Most of the given techniques fail to produce much sensation, even when applied over long time periods.

So today I got profoundly stoned, put in my Progasm, and just tried to relax into things. So far it isn’t unpleasant, but I still feel like something isn’t quite lining up to get me beyond “this is mildly pleasant” territory.
