I've not had prostrate surgery, but I have had four operations in two years to remove cancerous tumors in my bladder. These operations don't involve cutting and stitching but still require similiar healing time. I was advised to taked it easy for four weeks, which worked out fairly well. After the second bout, I pushed it and went back to work (heavy truck driving) after three weeks, and had bleeding and frequent peeing problems. So my advise to anyone, don't push it too soon or hard, follow the doctor's advise, they have many, many cases from which to draw guidelines from.
