personally i think it was a great question...
i am firmly convinced it only depends on the attraction of two people to one another regardless of anything else
i am white and in the last couple of years have had great sex with a few ladies of a different ethnic background to my own..... but it was the person that attracted me first and the frantic passion of ripping clothes off came after.
hope u get to enjoy some good swinging with some nice people of whatever colour
