good morning Len!
i don't want to seem overly pessimistic, but the reality of the situation is: it could (and often does!) take a couple of years to get that function back! of course, some never do get it back, due to damage (from the surgery and from the PCa), but from what i'm hearing, most guys get back with the program after MANY months.
my situation, for instance: my open RP was in January of 09, which puts me, what, 16 months out ? i am often getting nocturnal erections, and just within the last few weeks, with some excitation, it will sorta stand up on its own, not enough to operate like before, but an erection-on-demand is, for me, BIG PROGRESS, as you can probably imagine.
it seems like every month, it's closer to what i'm expecting/remembering, and my story seems to match with others i read, so i'm just hanging (so to speak) in there! of course i give it other exercise, which i assume helps the cause also...
doc has me on the daily cialis 2.5, and i occasionally pull out the pump and help open up the blood passages, but from what i'm hearing it just takes TIME for those nerves to repair.
about 5 years ago, i had Bell's Palsy, (where half your face goes limp), and maybe that helped show me that nerves back at their own special rate, and you just can't rush it!
just for your info, i'm coming up on 57 years now
anyway, i wish you all the best, but all i can say is you can't speed up Mother Nature (or is this more like Father nature ??)
have a good one,
