First of all, let me say that I think we all know that our
experiences and reactions are different, so please do not use my
report to cross Caverjet off the list of things to try for dealing
with post RRP erectile disfunction.  I would say try it, based on your
doctor's recommendation, so you know for sure if it works for you.
Unfortunately, it did not produce the results I expected.
    I had the injection this morning (male nurse) and what I
experienced was more like a pressure in the lower two thirds of the
penis, not in the head.  The pressure went down in to my testicles.
This was definitely not like a normal erection, and there is no way I
could have enjoyed intercourse with that discomfort.  The effects
peaked after about 30 to 40 minutes.  It started to subside after
about an hour.  It is two hours after the injection now, and I only
have a little ache down there.  I am back at my desk working.  
    This was similar to what I ran into with MUSE, except ten
times worse.  The main shaft of the penis became stiff, but it did not
produce what I consider to be a normal erection.  The length was
definitly not what it used to be.
    So, at this point it looks like the pump is the last resort (I
guess abstinence is really the "last" resort).  At least I tried.
    Thank you.
