loong-c 如果避孕,sex的是不是就没有外蕴价值了?我觉得还是有的。我觉得除了肉体感官本身的快感之外,sex还是一种仪式to express how attractive your partner is to you, how much you like your partner, how well you will treat your partner, how close you want to be with your partner. (Sorry for I must express those thoughts in English. Because they are never present in Chinese context.)
