The example may be misogynistic, but the idea that the example is an example of is not.
Also, suppose that the genders were removed:
X: “If I gave you a million dollars, would you sleep with me?”
Y: “A million dollars is a lot of money, and you don’t look that bad, so I guess I would consider it”
X: “Ok, since I don’t have a million dollars, would you sleep with me for $100?”
Y: (outraged) “What kind of person do you think I am?”
X: “We’ve already established the answer to that question. Now we’re just negotiating the price”
Now who is shown in a less negative light, X or Y? I'd say Y. Of course Y is also shown in a negative light.
