Why do you think women lie about it? People lie for personal gain or out of fear ...
Sex and maternity are literally the ONLY cards women can leverage over men - and even then, just barely. So they desperately hold on to the only thing possible that gives them any sort of advantage.
Take that away and what do women have? Fuck all. That's hyperbole, but my point is that men are the prize.
Also, as said, women are NOT told they can't be sexual, and women are NOT slut-shamed all the time [when they are, it's mostly by other women]. But women are TOLD they are told this all the time, so it becomes confusing to them, I'm sure. Just like #MeToo horse shit confuses men. Now, 25% of millennials [likely mostly men] think asking a woman out for a drink is sexual harassment.
I don't even know how many stupid articles I've read stating that "Women are told they can't be sexual. Women are taught to BLAH, BLAH, BLAH...", while literally reading zero articles actually telling women this.
Just like all the bullshit articles telling White people that racism is everywhere, when it's Whites who face literally four bureaucracies for racism at every public and corporate sector job, in addition to overwhelmingly comprising the majority of interracial violence victims.
I swear, libs live in La La Land.
