One of our best friends married his former booty call, which we think is kind of sweet. After all, what better prescription for a happy marriage is there than finding someone you lust after like an animal...and then discovering, oh joy, that you kind of like doing the crossword with them too? But much as we love this story, we always feel a little bit guilty telling it, in case we're spreading false hope. Because really, how often does a booty call blossom into a full-on relationship? About as often as we laugh at Ann Coulter's jokes, most likely. And usually it's less of a "blossoming" and more of a drifting into a sort of a common-law relationship where you're not quite dating but you're having sex and sleeping over and going for breakfast too often together to fit anyone else into your rotation.

So, what are your rules for making sure that a booty call stays just that, rather than mutating into a dysfunctional, it'll-end-in-tears pseudo-relationship? Do you wait a certain number of days between dates? Do you avoid seeing each other in daylight or sober? Do you not know each other's last names or day jobs? Do you greet each other with a cheery "Hey fuck buddy!" and a high-five?
