Hi there, thank you for posting your question on Ehealthforum. This is not intended as a substitute to visiting your own doctor.
Don't bother seeing a urologist just yet. Your subconscious "habit" of looking at yourself trying to get an erection has spilt over from your last relationship to your new one. You have a degree of erectile dysfunction brought on by Performance Anxiety or watching yourself trying to get an erection. You have three choices now. You can do any one or all of them.
(1) Do nothing and wait for it to right itself. Remember, most erectile dysfunction goes away of its own accord eventually.
(2) Go to a doctor and stay on something like Cialis 20mg. This "works" but understandably you do not want to stay on it indefinitely.
(3) Go to a Sex Councillor and learn how to get round Performance Anxiety through behavioural techniques. These typically involve stop/start erection management and eventually having intercourse with the lady on top doing all the work while you just lie there doing nothing. If you are not expected to perform then you cannot have any performance anxiety. A sense of humour too of course always helps. Talk to your girlfriend, give her a challenge.
I hope you found this of some help.
Dr Andrew Rynne.
