Welcome to the forum. I am sorry to hear that your surgery was so full of complications. It must have been an unbelievably rough year for you. Helpfully the worst is behind you now and life will start to look brighter.
My husband is only a week out of radical prostatectomy, so at this time I can't answer you erection question. There are many experiences here though, and I'm sure you will get some good input on this subject. Hang in there!
