" Imagine that the brain and the genitals are a couple of friends on vacation together, wandering down the street deciding where to have dinner.

If they're women, it goes like this: The genitals notice any restaurant they pass, whether it's Thai food or pub grub, fast food or gourmet (while ignoring all the museums and shops),and say, "This is a restaurant. We could eat here." She has no strong opinion, she's just good at spotting restaurants. Meanwhile, the brain is assessing all the contextual factors [...] to decide whether she wants to try a place. "This place isn't delicious smelling enough," or "This place isn't clean enough," or "I'm not in the mood for pizza." The genitals might even notice a pet store and say, "There's pet food in here, I guess..." and the brain rolls her eyes and keeps walking.

[...] Now, if the friends are men, it goes like this: The genitals notice only specific restaurants -- diners, say -- and don't notice any restaurants that aren't diners. Once they find a diner, the brain says, "A diner! I love diners," and the genitals agree, "This is a restaurant, we could eat here," unless there's some pretty compelling reason not to, like a bunch of drunks brawling outside. "
