Up until I was 60 years old I never had a problem with getting an erection and share it with my wife. My tool when erect was about 1/16 th inches short of a proud six inches. At sixty, I began having prostate problems like my father before me. I was diagnosed with prostate cancer, and the only option was surgery for the fast growing tumor. In the post surgery adaption the Medical Facility put me through a program to help me restore my erectile function. A combination of diet and erectile medication, plus an erectile pump improved my situation, but sustaining an erection was still problem. It was recommended to buy a small (Cir 5.5") realistic dildo to use after I take the pill. Sometimes I put it into my mouth while watching porn. The most effective action is to put a condom onto it and insert it into my anus, resulting in an erection that I can achieve penetration with my wife some of the time. In addition I lost about 45 pounds started an exercise program. Everyone is different so it is not expensive to try something different.
