This troper suspects that, by the toss of a coin, he lost the chance to have sex for the first time. Admittedly, it would have been with a friend he hadn't met for over five years, but had seen frequently until he was six (whereupon he moved to another part of the country) and
she was roughly four years older than he was, so, if it would have happened, I would probably be typing on the BigLippedAlligatorMoment page about how I swore not to mention it. To quote SimonAndGarfunkel, every way you look at it, you lose.
