I too had urinary issues for several years before my RARP - slow flow, never quite finishing etc. Never diagnosed with any infections but my first echo scan did indicate a slightly enlarged prostate.
After the RARP and after the small amount of debris cleared itself from the urether, I now pee like a horse. From always having a peeing problem, the ability to stand there like a hosepipe and completely empty is extremely satisfying.
I would also add that for me, prior to RARP, my orgasms were not particularly satisfying - I never ejaculated large quantities and afterwards, it would leak out for several minutes, a drop at a time. Basically it was a pretty messy affair. Now of course there is nothing being ejaculated and the orgasms have become far more enjoyable, especially being kept 'on the edge'.
