I used to think there were two separate entrances to the vagina, a front one for "missionary" congress and a back one for a "rear entry". Despite some perfectly good sex education and being no stranger to the occasional soft-porn mag, I held this belief right up to the age of 15, when my best friend rang me up to explain the true situation having just reached a "breakthrough" with his long-term girlfriend that afternoon. Then again, he appeared to have been labouring under a similar misapprehension himself: "It's not at the front," he said excitedly. "It's underneath!"
