Below is anecdotal evidence that (v.s. simply having a natural desire) being sex obsessed even in secret is not universal, nor "natural" nor necessarily caused by societies that hold traditional values (which 'sexual repression' is sometimes a euphemism). Rather if you look at google search statistics it is the most sexually liberal countries that are privately most sex obsessed, (probably as a result of public bombardments of sexual imagery and innuendo). This should not negate evidence that those cultures which have monastic attitudes to sex, severely shun all talk about sex, view it as inherently "evil", or "worldly", or not praiseworthy even within any form marriage, and strictly utilitarian for breeding purposes have sexual abuse problems (Saudi/Indian/Pakistani/Bengalis take note!).

Google.cn word search results: Chinese shun sex search for a good, old-fashioned bank
The Chinese appear to have dismally failed to grasp the primary use of Google, with searches on the word "sex" ranking way down the list of most-Googled terms in the country last year.
Leading the overall searches list was "QQ", apparently an "instant message service and a brand of car", according to Reuters. Next up was the China Merchants Bank, closely followed by the Industrial and Commercial Bank of China. Fourth place went to "stock" (as in "and shares", etc).
What merited fifth spot is not noted, but we suspect it might have been "anti-corruption". In keeping with the locals' evident love of banking, China Construction Bank came sixth.
All of which left "sex" out in the cold with an unspecified placing, much to the delight of China Daily, which was quick to point out that it was the "most popular keyword for Google users in some other countries".
In further revelations, Google.cn said that "China's Central Bank, the Ministry of Finance and Banking Regulatory Commission ranked first, third and fifth in the 'Most Popular Departments' list", while "what is a blue chip" and "how to invest in the stock market" topped the "seeking knowledge" category.
