Areo: Sex, Love, and Sexual Autism

Sex came first. It arrived before any concept of self or other, before there was care for anyone at all. And certainly before love. Sexual reproduction first evolved 1.2 billion years ago, eventually cropping up in our lineage 500 million years ago, give or take. There are two kinds of us: male and female. These names that we have given to the sexes are human terms, but they describe a reality that is far older than any language.
