Hi there, thank you for posting your question on Ehealthforum. This is not intended as a substitute to visiting your own doctor.
I think that you have developed a degree of performance anxiety erectile dysfuntion and that you have been pushing yourself just a bit too much. If you find yourself watching yourself and wondering how things are going down below, then that is performance anxiety. It will pass. If not go see a doctor.
Dr Andrew Rynne.
