You could always respond with a list of your own strange sex laws from around the world and in her neighborhood.
For instance, did you know:
In London, it's illegal to have sex on a parked motorcycle.
(If the motorcycle is moving, go for it!)
In Indiana, mustaches are illegal if the bearer has a "tendency to habitually kiss other humans."
(Ever looked in a dude's beard after a meal?)
It's illegal to have sex with a corpse anywhere in the United States.
(Hey, tough beans if you don't like it. Move to Canada! They have cemetaries there too, ya know.)
An 18th century French prostitute could be spared punishment if she were willing to join the opera.
(Those must be orgasmic auditions.)
In Minnesota, it is illegal for any man to have sexual intercourse with a live fish.
(No, don't even go there. I don't want to know. Oh alright. Dead fish are okay?)
In Oxford, Ohio, it's illegal for a woman to strip off her clothing while standing in front of a man's picture.
(What I want to know is who is the guy that proposed this law and how did he convince others to vote for its passage?) (Now this is one you could ask her about as another conversation starter.)
