I think you have a point, and I think it applies to some women as well, but I don't think it is everyone.
There is nothing wrong with casual sex as long as everyone involved knows what is going on.
I think the issue is that far too many women confuse sex with love, it's a part of our biochemical wiring related to all the hormones released due to orgasm.
The whole mechanical thing about sex, just having sex for having sex cause you are horny, well, each to their own. Again, nothing wrong with it, but really, it is more just about basic biological wiring, really primitive, and ultimately, not really all that satisfying, sort of like masturbating with someone else.
There is still a HUGE double standard for women who have a high sex drive and only want to have casual sex.
