To a woman, sex is like the garbage man. You just take for granted the fact that any time you put some trash out on the street, a guy in a jumpsuit's gonna come along and pick it up. But now, it's like a garbage strike. The bags are piling up in your head. The sidewalk is blocked. Nothing's getting through. You're stupid.
