Is there anything else available apart from prescripttion drugs that can cure erectile disfunction?

It depends on what is CAUSING the ED.

Have you spoken to a doctor to rule out medical causes?

First, you must know what the Cause is. The ONLY way to know is a doctor. They can tell you, none of us can, we aren't doctors.

No, not unless the DOCTOR has diagnosed the CAUSE of the problem first.

First often for some there is no cure, there is merely medication that will allow you to have an erection.

I have personally found, ( I normally use viagra) that a few of the over the counter products do help some, But finding the issue first is important
