Introduction to SGO is a PDF document explaining the basics of sex, gender, and orientation and defining the most common identity terms. It is designed to be simple, reasonably accurate, and easy to understand. Warning: Although this is intended to be as accurate as possible, it is also simplified in order to be easily understood. As such, it may contain too much gender binary for some people's tastes.
