The marriage age for men in the Chinese palace generally did not exceed 18 years old, with most being between 13 and 17 years old. Almost all emperors, young emperors, and crown princes had already consorted with women before their official marriages, possessing proficient sexual experience; some had even already fathered children. Sima Zhong, the foolish Emperor Hui of Jin during the Western Jin Dynasty, married at the age of 13 while he was still the crown prince.
