After reading the question from the guy in India who wants to marry his first cousin, I started thinking about why I have no sexual desire for any of my female relatives.
I have a niece and a first cousin who are in their late teens. They're both hot, but my cousin is Miss America quality.
She's prettier than most girls I've ever dated, but I don't have fantasies of her and I in bed. When I was a little kid, I had a crush on a 12 years older girl relative whose great grandmother and my great grandmother were first cousins. That means we don't share enough of the same DNA to cause potential birth defects.
My question: Is there a biological sense that keeps us from being attracted to relatives who share too many of the same DNA in order to prevent birth defects? Most animals, humans included, usually resort to incest if there's not much choice in mates. Therefore, risky birth is better than no offspring at all
OR, are we just drilled from birth into believing it's wrong?
