I'm more confused than you, because
I read the first chapters of the novel (the part about the wedding night) and it is said that
he was so "excited" and in "frenzy" mode (sorry, but I don't know how to describe it) that he did the deed without discovering anything. I mean Shen Yu was relieved because his cover was safe

Okay so I went ahead and read the first few chapters in the novel. And just like you said, it really seems that way. But lol whut XD I'm not sure what the author has in mind, or whether the author has zero experience when it comes to this kind of thing, but there is just NO WAY for someone not to know the gender of the one they're having sex with. So i really don't know what to think here hahaha XD

I mean otherwise the prince is very intelligent, fierce, powerful, had alot of concubines , has a wife etc etc ...but here the prince could not notice the difference after having s*x with the mute boy (having no boobs as well!) multiple times.
Unbelievable that the prince doesn't know at this point !!!
I think the prince knows but wants to keep it to himself.
Okay so I'm extremely deeply confused right now. Does the prince know Chen Yu is a man and not a woman?? I mean, they've been having sex and I'm confused as hell.
