The Eastern civilizations of long ago are much different than the cultures of today. Their way of thinking about women and men's roles were somewhat warped in our eyes. Religion plays an enormous role in the moral standards in the eastern civilizations whereas nowadays religion does not contribute quite as much.
In China the clouds and the rain describe the heavens making love to earth, which is beautiful. This is how the Chinese view sexual intercourse. The three most popular religions were Confucianism, Dowism, and Buddhism. Confucianism was the orthodox religion of the country, which is family oriented. The Ying and the Yang was believed to be in men and women; men having the semen and the women having sexual energy, which occurred before orgasm. There was a manual that came out to guide men on perfecting sexual acts with 30 different sex positions. This is similar to our society today, except we have pornography to graphically demonstrate the practices. Similar to the U.S. culture of today, the practice of polygamy was very rare. There were brothels where men socialized and often did business with one another. The brothels were more or less whorehouses, which we used to have not long ago in our country. Adultery was illegal and if committed by a woman she was killed. A fetish among the Chinese became small, bound feet. A dancer in 1000 AD started this trend which lasted until the 19th Century.
Two gods, one male and one female created Japan. There was no concept of original sin in the Japanese religion and culture. Family was the most important aspect of life. A man could have sex outside of a marriage as long as his family was taken care of. The husband of a family often had a prostitute, which played the vital role of relieving stress in his life. Prostitution was regulated in the 13th Century. There were also Gasias, which sang, dance, participated in religious ceremonies, and had sex for money.
