I am unable to have an erection in the morning. I have been to many doctors and taken all the tests and I have not been able to figure out what is the cause of my problem. Does anyone have any ideas why I would have erectile dysfunction in the morning?

I can always have sex at night, but sometimes I don't get as hard and I don't last as long as I used to. In the morning, I can't get an erection at all.

I am 36, I exercise everyday, I have never taken alcohol, tobacco or drugs, I am perfectly healthy (other than this one problem). I feel fine in the morning. I can get out of bed and run a 6 minute mile, or a 5k in 20 minutes, but I can't get an erection in the morning.

My testerone levels are fine. I don't have a cholesterol problem. I don't have diabetis and my blood sugar levels are normal.

Any ideas?
