Jiang Lu had heard that in history, especially among the eunuch community, some, though unable to perform marital duties themselves, took pleasure in watching others perform in front of them.
It's like taking out one's food and offering it to others for enjoyment while sitting to the side and watching, not knowing if it's a matter of vicarious experience or something else, but finding joy in just that.
This predilection made Jiang Lu think of a special group—Luomao.
It is known,
eunuchs have never been virile, and Luomaos are unable to be virile unless they see someone else behind their lover.
Eunuchs like to watch from the side, and so do Luomaos.
The life of a eunuch is not something ordinary people can accept, and neither is the life of a Luomao.
Eunuchs are slaves, and so are Luomaos.
Therefore, Jiang Lu had a startling realization, Luomaos are approximately equal to eunuchs.
