I can see it now---we are in bed, and you say, "Wait! You said...!" And I'd have to respond, "Well, a baby horse--a colt--would it not have a penis the size of a human male?" (Oh well----in Asia all the girls thought I was pretty big...) Back in the 1980's I saw a Chinese movie about a man who had a horse penis attached to replace his severed one. And he would pleasure all the girls. It was a typical martial arts comedy with sex and Taoist Priests and so forth. I don't remember a whole lot about it, but it was funny. I think the Chinese title was, The Man With a Horse Penis, or something along those lines. Anyone who knows much about the sexual history of China would know that for much of its history, they believed that men must have sex in order to have a long life, or even, as the Taoists often tried, to achieve mortality. Therefore, every woman of the household is fair game for the master of the house. The idea is to gain yin from the female, so it was also important for the female to orgasm, for this released her yin. The forehead of the immortals is tall because they have accumulated a lot of yin. Chinese art is filled with sexual symbolism. So much so that it is interesting for me to entertain everyone at my table, while waiting for the food in a nice Chinese restaurant, with all the symbolism filling the art on the walls, entrance way, and so forth. The peach and the peony rose, for example, are symbols of the vulva. And Chinese paintings with rocks and cliffs are typically filled with phallic shapes. It is even more interesting if you can read the Chinese. About 15 years ago in a Chinese dim sum restaurant I fell in love with a painting. The Chinese read, the gate of happiness, or something like that (it might have even read the Gates of yin, but that could be overly blatant----a common Chinese word for vagina is made up of two characters---yin and gate). I forget exactly what the painting was, but I believe it was a water fall or something in between two cliffs---which, after reading the title, I quickly realized that it represented a vagina. I asked the owner if he would sell it, and even offered a good sum for it, but he refused. It is all part of, after all, fertility magic. He probably placed the picture on that spot for abundance, which can also mean an abundance of customers, and money.
Wow! That really gives a new view for me into Chinese culture! I wonder much much yin I have left to give?
