We could go back to Sophocles but the warnings ramped up in Europe in the 1800s:
"There are people in Europe who, confounding together the different characteristics of the sexes, would make man and woman into beings not only equal but alike. They would give to both the same functions, impose on both the same duties, and grant to both the same rights; they would mix them in all things–their occupations, their pleasures, their business. It may readily be conceived that by thus attempting to make one sex equal to the other, both are degraded, and from so preposterous a medley of the works of nature nothing could ever result but weak men and disorderly women." - Alexis de Tocqueville (1805-1859)
It changed the nature of it.
What you are describing was best collected and analyzed by Joseph Daniel Unwin in his 1934 treatise, Sex and Culture, in which his general observation was that every empire he studied eventually liberalized female sexuality and then collapsed within thee generations thereafter.
Very insightful and accurate observation from de Tocqueville IMO, from almost 2 centuries ago.
