Can most women be bought? NSFW

[Tweety]

What percentage of American women, aged 20 to 55, would be willing to have standard sex (let's say oral followed by vaginal intercourse) with a complete stranger for $X, with X representing any amount of money they request? Assume the stranger is a reasonably good looking, disease-free hygenic guy in the same age group.

Put another way (the inverse), what percentage of American women in that same age group would not, under any circumstances, have sex with a normal guy for any amount of money, regardless of how much it were?

What conclusions can you draw from your projections?
