Many women are upset some men just want to "use them" for casual sex. I've seen a lot of complaints on here about men not being sexually trustworthy. I do empathize with that sentiment. But post-sexual revolution women need to expect this. We live in a time where large numbers of adult males expect and assume that they can and will have casual sex with no strings attached because other men do. It happens all the time at parties or concerts. Large numbers of young adult men are aware of the fact that some women really are okay with casual sex and one night stands and do those things. They also see women online talk about why "slut shaming" is wrong and how "high body counts" are fine. If at least some women are going to cheer on female promiscuity as empowering, don't be shocked by men going out and trying to find those women, live that kind of life, and get frustrated when if it doesn't actualize for them.

The sexual revolution promised more, better, and guilt free sex. Many young men want to find short term partners. The fact that it seems like a majority of women would still prefer sex within a relationship (but they still end up having at least a few one night stands) leads to this confusion. As long as there is always some non-0 chance a man, unconstrained by morality or commitment, can have sex and walk away he will likely take it. Over the course of a lifetime most women will have some casual sexual encounters and many guys are hoping to be the man in those encounters. There is no obvious way to undue this. Women who want commitment have to now deal with a high degree of uncertainty about a man's intentions. Men who want commitment have to deal with heightened female scrutiny. Women who want casual sex can have it relatively easily, if they choose. Men who want casual sex can get it if they are basically willing to play the numbers game and face a lot of rejection.
