I am suffering from the same problem. However, It isn't a psycological issue. I literally felt a muscle snap and i pretty much feel the same but the exact same issues. Did your husband ever lift wieghts? That might be the cause and snapped without him knowing it. I still haven't figured out who or how to fix it.
Hi,
Impotence may be diagnosed if the condition has been present for at least 6 months at 50% of the time. There are several causes of impotence.It may be due to psychological disorders,neurogenic disorders,hormonal and vascular disorders,venous and sinusoidal disorders.Drugs containing ephedrine, epinephrine, norepinephrine may cause impotence.Diabetic and renal disorders may also lead to impotence.
I suggest you seek a urologist's consult so that proprer evaluation be done on your husband.The treatment for impotence depends on its underlying cause. A visit to a sex therapist or psychologist may also help you both go through this.
I hope I am able to help.
