I just turned 50. I began to experience difficulty in achieving an erection about a year ago. Although, there are times when I wake up in the morning and I do have an erection. It's something that occurs on it's own and not by arousal. I still feel the need and desire to have sex as normally as always. But, I cannot achieve a hard erection as before. It does try to become erect, but it's more flacid than anything else. Can this condition be cured? Or, is this the type of condition that can only be treated to help achieve an erection? More specifically, is it something that I have to live with for the rest of my life?
