Third paragraph reads:
“Much of the theorizing of the nineteenth century viewed homosexuality as either willful sin or a biologically determined sickness, with the common explanation being that homosexuals were another sex, different from male or female, and more akin to hermaphrodites and other individuals with genetic or structural anomalies. This confusion, along with a merging of gender identity or transgender phenomena with sexual orientation variation, continues to haunt and confuse the study of sexual behavior – about with more will be said later.”
