Society used to tell girls that sex was basically a thing that was done to you. Lay back and think of England etc.
Society evolved and eventually the idea that women could have as much fun (or more!) as men during sex came about. Eventually lads mags and then porn turned it around again to women being spunk receptacles that men do the sex to.
Just idly wondering, do you think that's why lots of young women are also calling themselves asexual and demi romantic?
Because it gives them a societal opt out that they no longer have?
