erectile dysfunction
"I had a failure in bed with my wife. It was after a Friday dinner, we had a bottle of wine and after a nice dessert went upstairs... well, it turned out I just can't have sex, just dead calm, if you know what I mean. My wife and I, we were both surprised and worried. 
I didn't go to the doctor though, after all it's just one bad night. On the next day it was almost ok, but I needed more time than usual.
