That is a very prudish and kinda hypocritical view of things to me. Applying the same standards Edwin would also be a whore and yet i don't see you complaining about him.
Again it seems you are making a judgment without actually playing the game as you implied in you post above.
All their stories are being explored and they will continue to be explored in future updates as the game progresses. They aren't just selling themselves for the sake of it as you say.
This isn't a generic corruption game were the protagonist is a dirty pervert who spies on his "landlady" and where every women goes crazy for cock at the first opportunity.
