This makes no sense because women today are more sexually free than they have ever been. In absolute terms women are still often slut shamed, but it's still less than in the past.
That's true but there's the woke / me-too movement now. I have a "friend" that I met from Tinder during early pandemic, we only met once because of it, and then it was purely sexting exchange of pictures and so on.
Last month she started following a local me-too movement FB group that had women sharing about their past harassment experiences and calling out their aggressors, that ranged from total abuse of power, to sexual innuendos over IM.
Last couple of times we texted each other mostly consisted of her showing me past screenshots of chats where someone (from Tinder) would be sexually suggestive, nothing explicit, and would start to tell me how she didn't realize that she was being harassed and that she's being disgusted by them.
Sounds like you’re on speaking terms still, maybe now’s the time to get that affidavit signed that everything was consensual. :D I’m kidding.. but maybe I’m not.
How far back does this millenials have less sex thing compare too? Today's women that grew up in the 90s yeah probably is more free then one from 50s and earlier. But compared to the 70s? I don't think it's farfetched to guess that society's feelings towards women sexuality have regressed since the sexual revolution of the 70s. Paris Hilton having a sex tape coming out was a huge deal, that's what millennial girls grew up with.
I don't mean to suggest that this is the only reason, I just think it contributes.
