So far it looks like the best way for me to warm up and get my prostate hard is to lay on my left side and do a bunch of PC contractions and lower ab pushes until my prostate starts to feel electric shocks like a chiropractors muscle machine. Then I can seek to find a muscle state that keeps the buzzing on constant, then really get good orgasms.
Sometimes, it really magnifies the contractions to take my hand and pull on my top butt–cheek to spread the cheeks apart. Don't know why this works, but it makes it really easy to feel every muscle movement inside my groin. Maybe it's just a mental thing or maybe it tightens up the muscles around the prostate.
Had the most intense dry–O's so far last night. Had tried yesterday morning to get my prostate to have the electric buzz, but no matter what I did, it just wouldn't go there. It was definitely being aroused, but something was blocking it.
That night however, it was different. Took 15 minutes of warmup, but then my prostate got rock hard – like I could feel a bulge inside my groin. I really want to refer to this state as the prostate having a hard–on. It really feels like that. In this state, it's super easy to generate an Orgasm…
WOW… Started having small Dry–O's, but I kept up the PC contractions, and it got to the state of electric buzz constantly. Then I could almost make any body part orgasm. Had a very intense and maybe 10–15 min constant orgasm by twiddling my abdomen just above the base of my penis and nipple stim. Took maybe 10 min to get the orgasm going, but then it took no effort to keep it going. It was like a constant thrust/contraction or "dry heaves" of orgasm, but there wasn't any semen. Very intense. Then I tried rubbing my G-Spot with nipple stim, and I had a slight Super–O of good feeling all over.
Finally ended it after 2 hours because I had enough. My prostate still had a hard–on though as I went to sleep!
Next morning I woke up and it was still hard!! I did a couple slow PC contractions, and the buzzing turned on constant. Did a little nipple stim, and immediately went into bounce and shake orgasm, so had a nice wake up orgasm.
Was a little concerned and I didn't want to stress anything though, so just got up. Last night was really intense, and I'd heard stories of guys pushing too long and ended up damaging tissue, so figured, I'd had enough.
I think one area of exploration I'd like to do yet is to try involuntary muscle contractions. I've only experienced those a couple times in a small way, and never after actually trying to get one to happen. I can imagine that if I was able to get those going after the prostate was constantly buzzing and rock hard, there might be a very intense orgasm around the corner.
