We all want someone to build a fort with. We want somebody to swap crayons with and play hide-and-seek with and live out imaginary stories with. We start out getting that from our family. Then we get it from our friends. And then, for whatever reasons, we get it in our heads that we need to get that feeling- that intimacy- from a single someone else. We call if growing up. But really, when you take sex out of it, what we want is a companion. And we make that so damn hard to find.
