Thanks everyone, I appreciate all the replies! I'm definitely open to other types beside simply Arab, so Hispanic, Italian, Persian, Indian, Pakistani... yeah those might be appealing as well. I know Toronto has a large range of diversity - I'd love to go sometime (and not just for swinging!)
Chicup, LOL I loved the graph - a nice visual representation of my prospects at this point (and I did see the yellow dot!).
I think some of you brought up a good point - that attraction isn't just a matter of skin color - people are attracted to a huge variety of different things. Mine happens to be tan skin, but I certainly need more than that to be attracted! And when you add four people's various preferences into the mix, it indeed can be a difficult task for two couples to all be sufficiently attracted to one another.
