Patient's question:
When I have sexual intercourse with my girlfriend, I often need her to stimulate my penis a few times for it to become erect. However, when I rest and try a second time, it takes a very long time for me to reach climax, and eventually, it becomes soft and I don't climax. Sometimes, it gets soft in the middle of it, and I feel very scared, with some lingering shadows! Also, could you please tell me how long a normal sexual encounter should last? I'm very worried about myself and hope experts can help me find the cause as soon as possible.Medical history: I often feel easily tired, which might be due to high work intensity. Additionally, whenever my workload increases, my lower back starts to hurt! First follow-up question.
Doctor's answer:
Hello: This may be Kidney Yin deficiency. Traditional Chinese Medicine (TCM) believes that Kidney Yin deficiency manifests as a weak syndrome due to insufficient nourishment and the generation of internal heat. The symptoms of Kidney Yin deficiency include: soreness and pain in the lower back and knees, dizziness and tinnitus, premature ejaculation and nocturnal emissions in men, insomnia and forgetfulness, dry mouth and throat, in the palms, soles, and chest (a feeling of heat), night sweats, flushed cheeks in the afternoon (feeling hot), yellow and scanty urine, red tongue with little moisture, thin or no coating, and a thready, rapid pulse. Treatment generally focuses on nourishing Yin and tonifying the Kidneys. Medications such as Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) and Zuoyuan Wan (Left-Guiding Pill) can be used. However, TCM emphasizes syndrome differentiation and treatment. It is best to consult a local TCM hospital for diagnosis and treatment, combining the four diagnostic methods () for optimal results.
