I honestly believe older human societies were matriarchal.
Do you think when we were fucking in caves before we even invented marriage or monogamy that people always knew who the father of a baby was?
Or that we even had the concept of specific fatherhood?
Probably not. But everyone knew motherhood was valuable still.
Those Venus statues of fat women were likely made by the women themselves (due to the shape of the body resembling the way a person looks down at themselves), these women were clearly respected and valued.
Women have our clitoris on the outside of our bodies because sex has a social bonding role in humans, hence the hormones released in the brain.
Back then they probably understood that PiV sex = pregnancy and probably only did it when they actually wanted to procreate because having a fuckload of unexpected pregnancies to plan for isn’t exactly an ideal situation.
There were probably many women who chose to never be pregnant since childbirth could be witnessed by just about anyone every time it happened and it would undoubtedly leave some women terrified.
