Have sex

Patient's question:

Each time I have sex with my wife, the first time I finish quickly, and then the second time lasts longer. What factors or medical conditions could be causing this? Also, what are the abnormalities during menstruation? Thank you!!! Frequently

Doctor's answer:

Hello, the first time it might be due to an increase in, leading to rapid ejaculation. The second time, the is relatively lower compared to the first time, so the duration increases. If you have other discomfort symptoms accompanying it.
