Non ejac.....?

I don't jizz during my super-O's unless I'm stroking for a super-T. My belly hardens and I start pushing against the belly contractions. I have my eyes closed, and things white out and my consciousness might go so far as to fill the room. (With Super-T's, it blows out through the top of my skull, splatters on the ceiling, drips down the walls and returns to me.) It takes at least four stroking super-Os, each bigger than the last to build a super-T for me these days. I get good solid erections for them, but they deflate between p-waves. I'm sure you can see the problems with intercourse.
Normally with just super-O's in an MMO, I get a small amount of pre-cum being milked from my prostate if an Aneros is in. I don't get the feeling of my gun getting loaded as fluids move to position during the phases of an MMO. Also, I don't get the endorphin shot unless I have a wet one. (although, I have that wet kind of relaxation and endorphins now without the fluid feeling, but I find a few drops on my pecker. It's evolving. I can get an regular ejaculation with about a quarter-teaspoon maybe after three days without one.)
Today, after the super-T, I had a couple of following at-least minis with shakes. Then I found my hands flapping involuntarily from the wrists against my chest for a while. First Time that's happened. Collapsed in an endorphin bliss-out under my Pendleton blanket for a couple of hours.

Dang....

You're likely to experience any number of different types of responses to your prostate being stimulated. These are but a few! Just let them happen and don't worry about if they should or not! It's a journey. I'm laying on my back right now totally blissed out on p-waves that keep flowing and flowing head to toe...just amazing feelings! Love it totally!

Yes like @theme_gasm said so many things will happen when you et go and let it all happen naturally. You will be surprised at what your body can do and sustain.

Its a workout tho, all the shaking n stuff... like i said above, dont know how some dudes in videos can go an hr or more doing so.

My first night with Aneros, I was racked with dry o's from about 10 or 11pm until 6am...countless full-body contractions and shaking of the legs...it was both amazing and alarming...as my body and mind were on hyper-reaction mode and I had awoken a sleeper within me! I felt like a whole new world had just been unveiled to me. These incredible contractions would not stop, even after I removed the Aneros...it was amazing! I still have full-body contractions, but they are part of a group of sensations that I cycle through depending on how long my session lasts. Over the course of an hour, it starts with a gentle fullness on my prostate area, followed by a tickling sensation through my anal canal and prostate, followed by p-waves for a good while (a wonderful state to be in), followed by involuntary leg or shoulder or stomach or all three contractions, and eventually by often sudden full-body rigidity and p-waves, rapid breathing, and multiple orgasms that hit hard, cycle down briefly, then hit hard again. At this point I can go on for as long as possible, going in and out of these strong full-body orgasms, or try to relax and let the p-waves carry me...it's my choice, but I'll take either if I have the time! Recently, the longest I will go is 3-4 hours...totally blissful and my body and mind feels so alive!! BigO seems to jump to some pretty amazing orgasms a lot faster than I do, based on his videos, which is what makes this such an amazing adventure...you just go with it!

Themegasm....i hate you and am jealous.....just kidding....still jelaous though....

Be patient with yourself and keep working on those kegel exercises! It makes a difference! Once your prostate wakes up anything is possible!

Same for me as with @WarrenGWonka.. my belly hardens and I lightly push against the belly contractions - AND relaxing into it letting it take me over at the same time. Until it finally gets to a point where I super O... then the multiple contractions anally and belly go by themselves..... sweet release and heaven.

no jizz or pee..

Sounds awesome.
