Well, I certainly never had such a relationship with any of my cousins, but...
look, from a simple historical perspective? It isn't as weird as most people think.
You can take almost anyone alive, and trace their family back 5 generations, and you will find a 1st or 2nd cousin marriage in there. It is a shockingly normal thing in almost every culture on Earth, and only became "taboo" in the last century. And even then, in many places in the developed world, it is still seen as acceptable.2
