Prostitution in Eorzea

[YianKutku]

There's structural sexual abuse in Ishgard - we've seen enough in the way of nobles' bastards to indicate that - but I suspect that actual prostitution, in the form of currency directly exchanged for sex, would be limited to the poorest classes.

Pretty much. There is a bit of NPC dialogue near the Brume where one NPC is utterly scandalized by the suggestion that he ever intended to procure the services of a prostitute in the Brume, but phrased in a way that suggests he was probably planning to do exactly that anyway.

So if it happens, it's not spoken of in polite company.
