"Women are not particularly sexual beings" is a quote from an (awful) book called 'Sex At Dawn' by Christopher Ryan and Cacilda Jethá. The book attempts to argue that women only have sex in order to get men to do favours like put up shelves or earn money, that women don't actually experience sexual desire or pleasure. The authors do not seem to have spoken to many women in the writing of his book, nor do they seem to be aware of the existence of the clitoris.
Horrifically, the book shot to fame in the USA and was heralded as one of the best books of the decade about sex. It was well reviewed by some equally ignorant men and negatively reviewed by academic scholars (and me). Alas, the misinformation about female sexuality spreads.
This book is far from the sole culprit. I've been consuming misinformation about my sexuality my whole life. "Humans are essentially sexual beings" is another nugget of knowledge I plucked from a book called 'Christian Theology' (of all things!) by Millard J. Erickson.
You do the math. Side by side, these quotes lead to the conclusion that women are not human beings. Oops.
