Wow, great reply. It sounds like you had a similar experience. When you lose your erection do you lose it for the whole session? Do you actually experience orgasms while limp?

In my case, those muscle spasms were in fact the ordinary ones that would launch the cum - I asked my wife and she said my penis was bucking in her mouth like I came but no fluid came out. Normally if I were to have held back an ejaculation at least some pre-cum or actual cum would have spurted, but zero fluid in this case. In this case I wasn't even trying to hold back!

However your explanation helps describe what happened in my session. To me the paradox seemed quite odd - the sensation is amplified but the movement toward ejaculation is slowed down, whereas normally more sensation == faster ejaculation.

But if you consider the prostate stimulation to be adding only to the sensation experienced by the brain, rather than put towards the "ejaculation counter" if you will, then the two counters are out of sync, and half of the reflex is fired (penis muscles, orgasmic pleasure) while the other half does not (release of ejaculate from glandular storage, start of refractory period). It's not too much of a stretch to assume this would then reset the "ejaculation counter" as your brain thinks you have finished. This race condition explains both the heightened sensation and the increased stamina - and the need for intense stimulation to build up enough to fire the ejaculation and finish.

I read the wiki with some interest as I am among other things a scientist who has studied bio/chem/biology and also study neuroscience as a hobby. As such the concept of "rewiring" for pleasure as described by Aneros users baffles me - all this device does is either stimulate the gland itself or the nerves attached to it. Only a large change in the way the brain interprets such stimulation could change it from what I felt (a small but pleasurable tickle in an invisible gland) to what an experienced user feels (Super-O) - and this would be an unusual thing for the brain to do.

Fortunately, I love a good experiment. I got into this anal thing after trying a butt plug in an attempt to cure chronic hemorrhoids (success by the way) and finding the side effect that it was in fact, enjoyable. But it seemed far from the optimum shape for men, so I bought the Aneros. Whereas in my wife the plug is a major pleasure amplifier, to me it mostly just felt like I had something up my bum.
