I have a question.. Did it give you the same "sick feeling" watching two females do the rumba dance? Probably not. I'm convinced that seeing two females in close contact dancing does not elicit the same viseral response as watching two males. Women have always been allowed to dance together, hold hands, show affection to one another that men are not allowed to. This, I believe is less to do about the males' sexuality than it is cultural standards... Particularly Western. Men in other cultures have more freedom to express emotion to one another.
