If we base the proliferation, acceptance of internet, digital porn on population, then I totally concur with you. However, if you have to put ethnicity groups on a scale from most "sex craved" in the eyes of the media or cultural stereotype to least, I don't think they rank top dog. Like the Japanese, if you have to compare the two which would you place on top? Similar analogy, Chinese being culturally conservative isn't typically(Sherry exlcuded ) associate with this stuff either. Does that mean Chinese lacks the drive and don't know how to do it? As for search terms, regardless of the ethnicity you search + porn you'll get hits so not entirely sure how that proves them otherwise. That's why I said blocking porn is a pipe dream.
