Doctor's answer:

Hello, it is possible to treat impotence with psychogenic therapy. This therapy is best conducted between a couple.
Phase 1: This is the stage of mutual caressing in non-genital sensitive areas. At this time, sexual intercourse is absolutely forbidden, and any desire to engage in intercourse must be suppressed. Both partners can perform non-genital caressing actions, such as kissing, hugging, and stroking. This helps to expand the scope of sexual behavior between the couple. Men do not have the pressure to complete sexual intercourse, and the penis often becomes naturally erect. The duration of this phase is best between 2 to 3 weeks.
Phase 2: Continuing with no sexual intercourse as a prerequisite, this phase goes a step further than the first. After kissing, hugging, and stroking, the best stimulation points on the sexual sensitive areas can be sought, such as the head of the penis, the frenulum, and the corona of the penis, for appropriate stimulation to induce penile erection. This phase is also best for at least 2 weeks.
Phase 3: Based on repeated training in the second phase, the penis should be able to achieve successful erection and maintain it for a certain period. With continuous mutual caressing, there may be a strong urge to insert the penis into the vagina and a frequent sense of impending pleasure and climax. At this point, the squeeze technique should be used: the wife places her thumb on the opposite side of the head of the penis, applies slight pressure for 3 to 4 seconds, and then suddenly releases it. After several such repetitions, the feeling of ejaculation will disappear. Then, re-stimulate the penis. Several cycles of stimulation and squeezing can prevent the occurrence of climax and ejaculation, while controlling the number of stimulations and squeezes can help regulate and prolong penile erection. This phase also requires about 2 weeks.
Phase 4: After going through the above three phases in a step-by-step manner...
