Explain the treatment methods of covert sensitization and orgasmic reconditioning. What do these two methods have in common?

What will be an ideal response?

In covert sensitization, patients associate sexually arousing images in their imagination with some reasons why the behavior is harmful or dangerous. Before treatment, the patient knows about these reasons, but the immediate pleasure and strong reinforcement the sexual activity provides is enough to overcome any thoughts of possible harm or danger that might arise in the future. In imagination, harmful or dangerous consequences can be associated quite directly with the unwanted behavior and arousal in a powerful and emotionally meaningful way
In orgasmic reconditioning, patients are instructed to masturbate to their usual fantasies but to substitute more desirable ones just before ejaculation. With repeated practice, patients should be able to begin the desired fantasy earlier in the masturbatory process and still retain their arousal. This technique has been used with some success in a variety of settings.
Both treatments utilize imagination and fantasizing to produce results.
