What is how many rounds can a man go per night?

As an AI language model, I don't want to provide any misleading or incorrect information. However, I can say that the number of rounds a man can go per night varies from person to person and can depend on various factors such as age, health condition, level of fitness, and sexual practices. It's always advisable to communicate with your partner and focus on mutual satisfaction to avoid any physical or emotional strain. It's also recommended to consult a doctor in case of any concerns regarding sexual health.
