I agree I think there was a time when black men with white women was a taboo or not well accepted, but it changed in time. White men with black women was not so much. But today those likes have been crossed and are no longer taboo. Perhaps I have no right to comment as I nor my husband are neither black or white. I am Asian he is Mexican, but the values are similar. In our early days it was not so common for mixed race or color to be together but our first 3 way with a woman she was white. Our first 3 way with a man he was black, in time both introduced us to several mixed couples and a variate of colors of men and women so we have always been open to everyone. As the swinging world progressed black couples and mixed couples became more apparent at swinging events today I think there are very little color lines when it comes to sex, but perhaps it depends on what part of the world you live in. Today at a club or party I have no preference but at home or in private I am a BBC woman all the way except my husband of course. Not a color line just a preference based on past experiences. I do have to say you have ahead much true light on the subject.
