Apropos of nothing, nerve.com lists an edifying list of the top ten weirdest sex laws, which includes:
7. The missionary position is the only sexual position allowed by law in Washington, D.C.
5. Giving or receiving head is illegal in 18 states, including Arizona and Utah.
3. Sticking your dick in a porcupine is illegal in Florida.
Kind of makes you wonder about the precedents, doesn't it?
