From Henan,
Thank you to the doctor for answering me quickly – How should I treat and prevent this?

Doctor's answer:

There are many factors or causes that can lead to insufficient hardness during penile erection, including kidney yin deficiency, kidney yang deficiency, blood deficiency, blood viscosity, high blood lipid levels, blood stasis, qi deficiency, prostatitis, emotional tension, and many other factors. It is recommended to consult a traditional Chinese medicine practitioner for syndrome differentiation and treatment with Chinese herbal medicine. If the issue is related to kidney deficiency, herbal pills such as Wuzi Yanzong Wan, Shenrong San Shen Wan, Shenrong Guben Huaoshao Wan, and Haima Duo Bian Wan can also be taken.
