I am a 61 year old male in good physical condition. I am 5'10' and weigh 160 lbs. I have been running and liftiing weights since age 13. Diet is free of fried and "fast foods", . Diet consists of app. 50% roasted chicken, fruits, veggies, some red meat and pork, etc. Problem is can't get erection 'when it's that time'. Erections during the nite are good. I just had my testosterone level checked. I t was 656. Your thoughts on treatment for this problem?
