Bashful bladder is: a social phobia experienced more by males but also by females. It is formally called paruresis and there is an organization for help at http://www.paruresis.org/ Clinical hypnosis w/self-hypnosis training by a clinical psychologist can be effective. See your doc first. Peace and good health. Remember, see doc for diagnosis.
