Just take a look at history. When the Europeans first came to The Americas, they didn't mix at all with the Native Americans because they had zero sexual interest in them. Same thing happened when Europeans sailed to India, South East Asia, Australia, etc., no sexual fetish developed with those people. However, when the Europeans reached and went to Sub-Saharan Africa, what did they do? Started having orgies with the native Black Africans, brought some others to their colonies like the U.S., Jamaica, Barbados, etc. as well and mixed with them (the average Black American is 20% White, same with Jamaicans, etc.) as well and look now, we have an irresistible BBC fetish, lol. There is a sexual intensity and tension between Blacks and Whites that is so great and almost indescribable.
