I think you've gotten your answers, but thought I'd throw in my experience. I've had only one REALLY intense orgasm post-op (4 mos now), and it was while standing. I noticed that I had some extra pressure in the area where the prostate used to be (internal muscles bearing down--kegel style). Apparently I was "tweaking" some sensitive tissue left over next to where the prostate was. That particular orgasm was also wet. Urine ejaculated in spurts, just like a pre-op orgasm.
Since then, I've usually been sure to empty my bladder twice
, if I don't want to deal with urine. I should note that I'm still slightly incontinent (2-3 pads/day). My Uro told me it's common for most men to retain urine after a single trip to the toilet. I found I usually retain at least another 5-15 ccs. I can get rid of most of that by waiting about
2 mins after going the first time and trying again. Since then, my orgasms are almost always completely dry, particularly if I'm on my back and depending on how long the "act" took (if I was actually making more urine in the meantime). (Being on your back should cause the least strain on the bladder and therefore the external urinary sphincter, as well.... I'm pretty sure "gut size" also has some bearing on the physics here, as well as overall core strength).
I will note that in my case I am certain there is some left over enervated tissue remaining after the prostatectomy. I'm 100% ED right now. I was able to achieve stronger orgasms pre-op by repeatedly/rhythmically bearing down around the prostate area with muscles (kegel), prior to orgasm... also using those muscle to stave off orgasm, if I wanted to prolong sex. I've noted that on occasion, post-op, I have been able to have a similar sensation be rhythmically contracting the pelvic floor muscles in that area. It increases the intensity of the orgasm considerably. I'm about
40% right now on whether I get ANY of those intense, uncontrollable internal contractions at orgasm. They happen way more frequently however if I concentrate on this rhythmic floor muscle activity. Otherwise, the orgasm/contractions seem to be much more externally focused... tending to involve only or mostly the penis (with maybe very weak or almost non-existent contractions internally).
