So I've been a big fan of prostate stimulation for many years. While I have yet to squirt oodles of fluid from prostate stimulation, I have had what I would describe as "mind blowing sensations" from prostate sensation - some leaving me in a state of unmovable bliss for hours after screaming my lungs out in extasy. No, no ejaculate came out of my penis, and I'm not sure if I would describe it as an orgasm, either...certainly not like a typical penis squirt orgasm. In either case, a wonderful sensation.
So here's what I did:
I used to use various toys, included plugs, but they never really did it for me. I figured they weren't big enough, so I kep finding bigger and bigger dildos or plugs or vibrators or whatever was handy, but they all pretty much just left my hole sole and my prostate unsatisfied.
Eventually I found the aneros, which is a lovely little toy indeed. I haven't had screaming results from the aneros, but it IS my favorite sex toy, bar none. I highly recommend it. It also happens to by tiny (at least by comparison to the fist-sized objects I was cramming up there before), yet provided more pleasure than most of the larger objects.
This lead me on a search for hard, small objects, and I ended up with a glass female g-spot stimulator that looks similar to this (but glass instead of metal): http://www.babeland.com/page/TIB/PRO...-hard/LO366521
I got it from babeland, but a local retail store and I don't see the exact model on their website.
In any case, this little bugger was just the thing - it first off allowed me to reach much more comfortably, because it gave me a longer handle. Second, it's curved "s" shape allowed me a much better angle for stimulation. Third, it's glass, so it's almost no friction, just pressure. Combined with lots of lube this took the sensaton off my hole and allowed me to focus on the pressure stimulation to my prostate. I found that a slight fucking motion while applying increasing pressure lead to mindblowing results.
Solo play is great, but it wasn't until my girlfriend got ahold of that handle that I went over into screaming extasy level - she was able to keep going long after my own muscles would have refused and left me absolutely happily incapacitated for hours.
Never found a cock that could provide anywhere near that much pleasure, though I still hold out hope for the "ultimate fuck". :-)
BTW, my girlfriend also loves the toy herself and it works great for her g-spot, too - similar mind blowing results.
I think that after playing with this for a while longer I will probably end up squirting something, it feels like there is a ejaculation-type peak in there somewhere, even though I have not yet found it.
Good luck, have fun, and remember to relax and use LOTS of lube.
