However, there’s another thing that happens, which is people have sex without charging one another. Here’s the crazy thing: this is not an exchange of a commodity but an activity that men and women both participate in, because it’s fun. People can and should have sex together, not just with enthusiastic consent, which I think doesn’t stray far enough from the commoditized model, but enthusiastic participation. Sex is not a thing than men do to women if the women say they can, and then the women just lie there like Snow White in the glass coffin, red as blood, white as snow, and black as the ebony in the window-frame.
[…] Women are not particularly encouraged to enjoy sex in our culture. Why? Because this economic model gets drilled into their head at every opportunity. Why buy the cow when you can get the milk for free? Sex is not presented as something fun two people so together but as a dog biscuit you dole out at various times until get the behavior you want: a marriage proposal. Because God forbid you ever have sex with anyone whom you’re not trying to trick into marrying you. Because if you enjoy having sex with various random guys just for the hell of it, do you know what you are? A slut!
