Basically, a guy's threshold to get aroused and be ready for sex is much lower than a woman's. Men simply need to get an erection and have an attractive enough stranger in front of them to want sex. They assume if they looked like Chad women would just strip off their clothes and start fucking them on the street because they project their own sexual arousal mechanism to women. But women have a higher threshold for sexual arousal. They need to feel comfortable, safe, it takes time, they need to be with the right guy who projects confidence so they can feel confident wjth him to experience the level of sexual arousal that men do much easier.

So the issue has never been a difference in libido, only a difference in the arousal mechanism and projection your own mechanism onto a woman and expecting she gets aroused the same way you do is a recipe for disaster.
