One of the weirdest popular ideas in this fandom continues to be that Nie Mingjue (raised in a heavily militarised setting where people seem to be free to talk about sexual subjects, his father had a wife and a concubine, little brother famously has a collection of porn) somehow knows next to nothing about sex while Lan Xichen (raised apart from women in a heavily regulated, monastery-like setting, raised apart from parents by an unmarried uncle, lives in an area where talk about sex was presumably banned or at least heavily taboo) is somehow the local sex expert
