What is the equivalent in Chinese for the English word "horny"? As Mr. Confucius said, 食色性也, food and sex play important roles in one's life, when you wants to eat, there is a word in Chinese 饿 to illustrate this state, but there seems no such a word in Chinese to describe the situation when you are horny, or perhaps there is, but beyond my knowledge. So anybody can help?
