The defense argument seems to be that the women had already agreed to provide sexual services and the matter is one of his refusing to pay the fee.
If I agree to have sex with a man, and we're in bed making out, and he calls out another woman's name, and I say, "Get the fuck out, asshole!" and he whips out a knife and has sex with me anyway, did he rape me, or is it a lesser crime because I initially agreed to have sex?
I realize this might shock the asshole defense lawyer, but women DO have the right to change their minds. Even prostitutes.
I think the first question would be, with your attitude, why would ANY man ever get in bed with you in the first place?
No, the first question is, "Why do you insist on thinking that your opinion is worth a puddle of warm spit to me?"
