The doctor introduces the couple to detailed anatomical, physiological and psychological knowledge of sex, focusing on the characteristics of the male and female sexual response cycle, different ways of sexual expression and how to arouse sexual excitement. At the same time, they are encouraged to discuss issues related to sex in order to seek a more consistent opinion. At this stage, couples should live separately from each other and sexual intercourse is prohibited, the purpose of which is to eliminate the state of anxiety about sexual activities. Step 2: Physical and emotional communication of non-sexual organs (3~5 days). After the completion of the previous step, both husband and wife should lie together naked, kissing, hugging and caressing each other all over the body, but taking care not to caress the breasts and sexual organs. Although sexual arousal often occurs at this stage, it is important not to have sexual intercourse and should focus on experiencing the pleasure of the entire body. In the last 1~2 days of this step, you can begin to fondle the breasts, but still do not touch the sexual organs. Step 3: Fondling of sexual organs and application of masturbation techniques (2~3 days). On the basis of the continuation of the activities of the previous step, both spouses look for the best sexual stimulation of their own sexual organs. At this stage, it is still important not to have sexual intercourse, but to experience as much physical and mental pleasure as possible during the operation, and gradually focus the sensuality on the sexual organs. Step 4: Therapeutic Sexual Intercourse Activity (4~5 days). After the above three steps are completed, you can have sexual intercourse for different sexual dysfunctions. When the man’s penis is stimulated and he is about to ejaculate, the woman puts her thumb on the area of the penile ligament, and her index and middle fingers are placed on the other side of the penis on the upper and lower part of the coronal groove.
