Having sex for a long time without ejaculation, and then it becomes soft again, and it's hard to get hard again.

Patient's question:

I want to ask what this symptom is, I'm very confused.

Doctor's answer:

Hello, friend. Based on the current situation, it may be caused by kidney deficiency. A detailed examination is needed to clarify the diagnosis. There is hope for a cure only if the diagnosis is clear. Rest, drink more water, and supplement more vitamins.
