I'm in that boat, I can actually orgasm more easily than before the prostate surgery, but I'm somewhere between limp and kinda erect. Of course no ejaculate, except for now and then, if I've been edged for a while, the cowpers gland provides some juice that is about like girl squirt. I'm bi, so i can also say that anal is still great, but it no longer gets me to orgasm by itself with no prostate to stimulate. But oral is as good as it ever was, and since I love giving as much as getting, it;'s still all good!
