4 months is far too early to be expecting normality to return. ED was the big thing for me as well. I wasn't worried about
the cancer as I knew that was treatable. It is difficult to stay positive when nothing seems to be happening and I remember getting quite down about
things on several occasions. Recovery from surgery is a long gradual process and you have to be patient. That is exactly what everyone on here kept telling me but I didn't feel like being patient as I wanted my erections back! I am now nearly 2 years on from surgery and looking back I can say that the time has gone much quicker than I had thought it would. You have to be thankful for small improvements and then be patient until the next little improvement. Everytime I seemed to plateau I would get worried thinking 'is this as good as it is going be?'. Only a few weeks ago I was getting worried as the 2 year mark approached thinking I may not improve any further. Then only a few days ago I achieved almost a full erection whilst lying in bed and without much stimulation
. I immediately pounched on my wife who was feeling tired but was delighted that our mutual friend had made another step in the recovery process. It hasn't been repeated since but this must be a sign that there is more recovery to be had.
So stay patient and enjoy each step in the recovery process.
