You need to join the "penileimplants" group on Yahoo Groups. There are over a hundred members who can relate very well to your experience.
I haven't had the surgery yet, but your experience so far is very common. The biggest after effect seems to be the six weeks of partial inflation, which for some men, can be very painful. I think it depends on how many surgeries one has had, if you tolerate pain very well, how active, etc.
I had by-pass surgery in 2005 so I don't expect the pain to be bad for me at all.
