Too many. Basically, in ancient times, princes who were still ruling the country over 40 had the habit of marrying concubines, so they could count tens of thousands.

But few women are older than men. Only Wan Guifei, the wife of Ming Xianzong Zhu Jianshen, is famous. Wanbida 17 years old. 18 years old had an affair with Wan before he ascended the throne. Interestingly, Xianzong had a special liking for the Wan family all his life.

Because in the ancient patriarchal society, unless you are infatuated and marry a widow for wealth, you always marry a little wife. Who will marry someone older than himself?
