I ordered a pizza once that, when it arrived, was not only twice the size I had ordered, and cut into more pieces than I could make heads or tails of, it also looked like the person who cut it had not exactly aced geometry. I think that pizza is a lot like our sexualities tend to be: a pie that turns out to be a lot bigger than we expected, and looks different than we expected, including a lot of pieces where the form is often largely indiscernible and rarely tidy or systematic.
