I'm blond-haired, blue-eyed and fair-skinned (with freckles--ugh). I've noticed that over the years, while I find men with similar features attractive, I'm also very attracted to men with pale skin, dark (almost black) hair and brown or blue eyes. I've never been one to go for the tanned surfer guy or brawny muscle man look--if I had to choose, I'd pick Loki over Thor any day of the week. My long-time boyfriend actually falls into the latter category--light-skinned (not pale), dark brown hair and dark brown eyes with a heavy brow. And really tall. He looks nothing like my dad or male family members.
I've been wondering if, at some instinctual level, that it's beneficial to be attracted to someone who looks different than you? I'm aware that for most of mankind's history we stayed within the same tribe/group and general area. Since I'm sure they figured out early on that it ain't right to screw your relatives, they would have mixed with other groups. But wouldn't that produce a kind of homogeneity within the people in that vicinity?
