My husband is pure and has few desires, but I gave birth to three children in a row

In my previous life, I was forced to marry, but on my wedding night, the man said that he was a eunuch and could not be human. He gave me two choices, one was to live as a widow, and the other was to let me go free. In my previous life, I packed up my things and ran away at night, but was murdered for money and died in a foreign land. I traveled through time in this life, but I know that this eunuch man in front of me will be a high-ranking official with great power and respect in the future. Marrying him only requires a few years of hardship, and then I can be an official's wife, without worrying about having children or concubines. It's perfect. So when the man asked, I didn't think about it and chose one, to live as a widow. It's just that although I didn't suffer much, isn't it a eunuch? But why are there a few more...
