The same principle applies though. She agreed to a certain deal, but upon arrival the deal was changed. She would be as much a victim as the tractor repairman.
“The same principle applies though.”
I don’t believe it does. The “deal” would not be something the repairman would ever conceive of offering up whereas the hooker would do so by definition.
Now if for example the prostitute would have been a “dancer” or “strip-o-gram” that do not routinely have sex with their clients in the course of their job and sex was “forced” it would indeed be rape as well.
