yes it’s part of their nature but society had measures in place to restrict their nature for thousands of years, women weren’t allowed to work or own property which meant that they were dependent on a man’s resources for survival, this gave men leverage over women hence women had to choose men based on wealth rather than looks.
Marriage as an institution existed to prevent whoredom and to ensure that the woman that each man was married to would only have sex with him and nobody else. Female virginity was prized and non-virgins had less value in society and were socially looked down upon. Girls were married off at a young age
all of these factors meant that a woman’s innocence in childhood continued on into adulthood, as she slowly transitioned from a playful little girl into a loyal, obedient and subservient wife who would cook, clean, have sex with her husband and give birth to/raise his children.
although it is female nature to be a whore, females used to be innocent and remain innocent for the rest of their lives due to societal pressures and the way society was structured, this shows you the power of nurture over nature. Nature is powerful but the environment that someone grows up in is even more powerful and has a greater influence on their behaviour/character than nature ever could.
You say it is female nature to not be innocent and that it’s inevitable that females will lose their innocence, but for thousands of years society forced them to be innocent, the reason they lose their innocence in the modern era isnt because it’s their nature, it’s because the restrictions which were previously placed upon their nature have been lifted due to societal changes, it is the twisted nature of the modern world (through gynocentrism and feminism) which has corrupted them and robbed them of their innocence which they would have retained in previous eras
