Is aversion to discussion of sex a part of traditional Chinese culture? Seems odd given I'm not aware of any puritanical religions taking hold there.

Because it promotes social stability ? As much as I dislike defending religion - those values produced the most stable societies through history
Societies of n>100s. By tabooing sex you reduce promiscuous behaviour - which stabilises society. I don't really see how this would be controversial. Modern social values have unambiguously shown that they lead to a population decline. Huge difference being that technology makes us less reliant on population count for stability (hopefully).
