Not only that but this problem can also be caused by physical aspects of your life such as smoking, obesity, heavy use of drugs and alcohol or lack of hormones.
If this is something you have already spoken to your doctor about but to no avail then the next step is to talk to a professional therapist. Understand that there can be many psychological causes to impotence that a professional therapist may be able to help you to overcome. If you feel uncomfortable talking to someone about your sex life then try to remember that therapists deal with this sort of thing all the time.
Hypnotherapy can help a great deal with impotence because it can help to undo and resolve any psychological conflict and underlying issues which may be caused the problem. It works in a similar way to hypnotherapy for anxiety and fear by talking to your subconscious whilst you are deeply relaxed and removing any negative associations from the past as well as asking your subconscious to act in a different way when put in a sexual situation.
