The whole idea of losing one's virginity is kind of ridiculous. To lose something implies carelessness. A mistake that you can fix simply by recovering the lost object, like your cell phone or your glasses. Virginity is more like shedding something than losing it. As in, "Don't worry, Mom. You can call off the helicopters and police dogs. Turns out - get this - I didn't actually lose my virginity. I just cast it off somewhere between here and Monterey. Can you believe it? It could be anywhere by now, what with all that wind.
