According to “Yu Fang Mi Chueh” (“Secret Codes of the Jade Room”), a Taoist sex manual written not long after the birth of Christ, it is possible to judge a woman’s sexual features by scrutinising her face”A woman with a small mouth and short fingers has a shallow porte feminine and she is easy to please. You can be sure that a woman must have big and thick labia if she has a big mouth and thick lips. If she has deep-set eyes, her porte feminine is bound to be deep too… if a woman has a pair of big, sparkling eyes, her porte feminine is narrow at its entrance, and yet roomy in the inner part… A woman with two dimples is tight and narrow down below…” etc., etc. It is interesting to note that some of the superstitions of ancient Chinese are current in modern Western society.
