Prostitute - to offer indiscriminately for sexual intercourse especially for money
A courtesan was originally a courtier, which means a person who attends the court of a monarch or other powerful person. The modern use of the term for a prostitute or mistress of a man of rank belies a much more complex heritage.
Escort (call girl or male prostitute), a sex worker not visible to the general public.
So those girls on AW who don't show face pics are escorts, the ones that show their faces are prossies, and the one's that change ££££ph and demand you be a city high-flyer or a arch-bishop are courtesans!
So that means she IS a prostitute!
