A middle-aged man walked into the clinic. “Doctor, I’ve been remarried for 1 year and I can’t get an erection.” I’ve been to many hospitals and had various physical examinations, but nothing is found, alas.” I carefully looked at Mr. Zhang’s past medical records and reviewed his previous examinations in detail: normal liver and kidney function, normal endocrine hormone levels, normal blood pressure, normal blood sugar, no abnormalities in the anal examination of the prostate and ultrasound. “When did you discover that your penis was not erect, and do you usually have sexual demands?” I asked. “I am usually in good health, and only after I remarried with my wife did I find that my penis could not get erect, and I usually have no sexual demands,” Mr. Zhang replied. To further clarify the cause of his illness, I asked him, “How was your sex life with your ex-wife?” “My ex-wife was my first love, we had a good relationship and a very harmonious sex life, it’s just a pity that she had a car accident just a year after we got married.” Mr. Zhang looked sad, and I asked, “Do you usually wake up in the morning with an erection or dreamy penis?” Mr. Zhang hesitated and said, “It happened a lot when my ex-wife first died, but then it became less and less frequent.” “So you haven’t had sex for 8 years, so do you often resort to masturbation to relieve sexual pressure?” “No, I have often painfully blamed myself for these 8 years and have not had at all.” At this point, the cause of Mr. Zhang’s erectile dysfunction (ED, commonly known as impotence) was basically clear. I told Mr. Zhang, he suffered from ED is neither psychogenic, nor organic, but “receding ED”. “This is a good way to treat this disease? I have taken a lot of drugs are not effective.” The first thing is that you can’t have any sex with your ex-wife after the accident, on the one hand, and never masturbate, the first physiological loss of the penis should be stimulated; on the other hand, because you miss your ex-wife all day long, which is the emotional loss of the necessary psychological stimulation of the penis. Thus, the sexual function appears “dormant state”, just like a machine, long-term shelving will rust. Human sexual behavior is both a physiological activity and a psychological phenomenon, which is regulated by the central nervous system. The hormones produced by the endocrine system exert influence on various parts of the central nervous system, which in turn regulates the work of these glands. Once the sexually sensitive areas are stimulated, such as touching, talking or thinking about sex-related things, the sexual arousal center of the brain will generate sexual impulses, mobilizing the endocrine glands to secrete sex hormones on the one hand, and instructing the lower sexual centers of the spinal cord to issue sexual impulses on the other. When the nerve center issues sexual impulses, the cavernous bodies on both sides of the penis contract strongly, thus blocking the venous blood flow to the penis so that there is no circuit for blood from the arteries, and the penis becomes engorged with blood and erect. As Mr. Zhang has not received any sexual stimulation for many years, the connection between the sexual excitement center of the brain and the lower sexual center of the spinal cord is not strengthened, and the secretion of sex hormones is often in a low maintenance state, and the penile blood vessels are in a “rigid” state of long-term contraction, making it difficult for the penile arteries to expand for a while, causing difficulties in erection. How to treat receding ED? I’m afraid this is Mr. Zhang’s main concern. In order to treat the need, I called his wife into the clinic, told her husband’s illness, told her to be gentle and considerate, with her husband to use the husband’s sexual concentration training therapy, to awaken his dormant sexual memory. The so-called sexy concentration training therapy is proposed by the American sexology master Mast, he pointed out: the couple should not focus on the erection and hardness of the penis, because when a person always pay attention to their penis erection, there is bound to be a strong sense of expectation, and this sense of expectation leads to anxiety inhibits the instinctive mechanism of sexual response, forming a vicious circle of anxiety-failure -The vicious circle of increased anxiety-aggravated failure. So sexy concentration training therapy especially requires couples to focus on the intimacy, caress and common experience of pleasure, and then to arouse the human sexual instinct. The specific treatment process can be in the following four steps: First, the non-genital sexy focus training phase. Stop making love, lie on the bed, practice touching certain parts of each other, but do not touch the breasts and genitals, focus on the soft and smooth skin, the lines of the body and body heat, engage in new non-verbal communication and arouse the intuition of the sexual officer, and then aroused sexual desire. Through mutual touching to achieve sexual concentration, improve the body’s sexual sensibility and evoke natural sexual response, generally training 1-2 weeks. Next is the genital sexual concentration training stage. On the basis of the non-genital sensual concentration training, stimulate the sex-sensitive area and induce the erection of the penis. During the stimulation process, prevent distraction and let the man have a sense of sexual enjoyment. Again is the vaginal accommodation stage. After establishing the genital sensual concentration training, you can try vaginal accommodation in female superior position and gradually transition to female activity, so that the male partner can feel the sensation of penis in the vagina. Finally, there is the sexual intercourse stage. Switch to male superior position for intercourse and complete the whole process of intercourse. A month later, Mr. Zhang came to the clinic again, and from his face full of joy, we could see that he had regained his old virility.
