Accents can help make the difference. I have yet to be sweet talked like I was when I dated Tatiana, a stunningly beautiful lass from Brazil. Truth be told though, I have a weakness for the lighter skinned northern European woman, in particular redheads.
I had an employee that was born and raised in Germany, her mother married a US airman and moved to the US when she was 17. Now in her early 30's she is still single. She is about 5ft 2in, 130lbs-ish with bewbs out to *there*, attractive, long curly dark brown hair, and as stubborn and a as much of a perfectionist as a person can be. It gets in the way of her finding a mate, she scares them all away.
