   Summary

   As it turns out, Spock's seemingly infinite knowledge is only that - seemingly infinite. She actually posses a few blind spots, most notably when it comes to the elements of Human biology which she does not share. After an unfortunate accident whilst sparring, she decides to brush up on Human genitalia and how it functions, and in the interest of efficiency, she asks Kirk to serve as her example.
