Blindly Dropped into Ancient Times, I Became the Chief Eunuch

Looking for a Novel With a Genuine Eunuch Male Lead

Looking for books similar to The Eunuch of Nine Thousand Years Is a Peerless Beauty. I once read a story about a real eunuch. The male lead sent the heroine several male attendants, but she wasn't interested, so she made them wait outside. When the male lead came back, he thought she'd already been with them and got furious.
