The Demand Curve for Sex
We now turn to the charts that university economics professors love to use in descriptions of the economy. Sexonomists have found these charts useful as well.
On the horizontal axis, we have quantity of sex. On the vertical axis, we have price. The higher you move on the price axis, the more expensive sex becomes. The further you move to the right on the quantity axis, the more sex is being done.
In an ideal world, all men would like to be situated anywhere along the bottom axis of the above chart, say points 1, 2, or 3. Why? Anywhere along the bottom axis, a man gets to choose any quantity of sex (bottom axis) for a price of 0 (vertical axis). This is free sex, a man's dream.
Let's illustrate the idea of free sex versus sex that has strings attached on the next chart.
At point A, the man gets free sex - 2 units of sex for a price of zero. At point B, the man gets 2 units of sex for the price of one - this sex has strings attached to it, a cost that must be paid. Which will he choose? There's no contest. He'll choose point A, because he gets the same amount of sex as point B except he needn't pay.
Though in their dream-world men would like to have free sex, in the sexonomy sex is a limited resource, and all limited resources have a price. We will discuss the intricacies of price more in a later section.
Given that all men must pay some sort of price for sex, problems emerge. Can all of them afford it? Unfortunately, no. Each man has constraints on the price he can pay for sex. These constraints might include things like the amount of money he has or the quantity of time he can spend to get some. A full discussion of constraints will come later on when we discuss price. If a man's constraints are too high, i.e. his ability to pay is low, he can't get sex. If he has few constraints, he can afford to have plenty of sex.
With our knowledge of constraints, we'll now construct a demand curve for sex.
If the price is 0, then a man will demand the maximum amount of sex he can get, since nothing is constraining him. If price rises to 1, he'll demand a little less sex because his constraints don't allow him to pay the price for what he'd actually like to have, but he'll still get lots. At price 2, the cost of getting some is even higher, so a guy will be even less willing to pay for the same amount of sex. He adjusts by lowering the quantity he demands, though he'll still get some. At price 3, the man can only afford a bit of sex. At price 4, you can see that quantity of sex is 0. The man has been completely priced out of the market; he doesn't have the resources that allow him to purchase any sex.
This is a downward sloping demand curve (which goes against our normal assumptions about slope - usually any whiff of free sex inspires one that goes upward). The law of demand says that in general, as price increases, demand for sex decreases. As price decreases, demand increases. In simple English - the easier it is to get some, the more a guy will want.
Next we deal with the law of supply.
