No, women have this mindset themselves, it is not coming from this generation of men, maybe those earlier boomer fathers or whatever.That type of mindset is exactly why many women feel a sense of entitlement simply because she has a vagina. And that her vagina is some precious commodity only given to those men who earn it by giving her a "relationship"?
There are men who will critisize women for casual sex but do it themselves. Its complicated.
The problem is simple. Women still think sex is power. This is the reason men are belittling themselves with 'seduction' which is really just clown game.
This is the reason why when a guy and girl is getting to know each other, he just cant come out and say "So we have known each other for x weeks, I think things are going well so maybe we should have sex" or something, but instead he is kept on his toes, not knowing if it is going to happen or not until it actually does.
There is also a weird idea out there, or maybe it is outdated now, that a guy needs to 'make it happen', have sex quickly, too slow to act and he is gonna lose the chance. All of this puts the women in an unbalanced high-power position, where her vagina has the most value in the whole relationship.
