So you'd say that when a prostitute has sex with someone, it's merely a physical transaction and she/he's not sharing a part of his/her self at the time and it is not at all personal? It depends on the sort of service the person in question provides. If some heart and effort is included in the fee and the bastard takes off without paying, I'd say that's rape.
You can't make a distinction here... I don't know too many sexworkers who just _fuck_. There's It's not an emotional violation, but it's still rape. Rape, on paper, is a physical thing. It leaves psychological scarring, yes, but on paper it's just physical. How bad it was shouldn't come into it.
