If you are in Shanghai in August you may want to drop in on China's Adult Expo. Apparently the Chinese are not squeamish about selling dildoes and other "marital aids" openly at train stations and other public venues.
In Southern China you can see old people selling huge dildoes and vibrators on the street. They are considered just one more medicinal product to be peddled for profit and the sellers do not have the seemy undertones that adult toy sellers have in the US.
The China Adult Expo website states:
"The time of being shocked at the mention of sex or regarding sex as an evil has gone by. Now in China, the civilized sexual concept has widely prevailed . A booming adult toys and reproductive health care market to 1.3 billion population, with incomparable scale, increasing trend and development potential, has come into being while sex has become one of the most popular topics for public discussion. Data pertinent to the current national sales volume of sex health care products shows that the latest annual turnover has exceeded RMB100 billion in 2003, and the rate of increase is approximately at 30%. At present China's adult toys market has entered an independent, professional and international new stage especially after China's participation in WTO."
