I find this interesting when you think America is considered to be much more prudish than Europe. Anecdotally it seems that although sex and nudity is less taboo in Europe it isn't abused in the way it is in America.
It's not really that weird, though; both behaviors are a result of a lack of maturity dealing with the subject, as taboos often are.
In a comparable situation, the Catholic countries which were/are more devoted (and often fanatic, such as in the Inquisition) are also the ones that have the most blasphemous slang and insults. Spain in particular has a whole host of them involving religious figures (God, the Virgin Mary, etc) and scatological acts.
