A courtesan is a profession which uses charm, refinement and sexuality to attract high status suitors, patrons and lovers. Though courtesans are almost all women, male courtesans are not unknown. They are found in the Free Cities of Essos, most notably Braavos, which is renowned throughout the world for its famous courtesans.
Braavos is also renowned worldwide for its courtesans, they enjoy high status and are famous worldwide.
Every courtesan has her own barge and servants to work them. The beauty of famed courtesans has inspired many a song. They are showered with gifts from goldsmiths and craftsmen beg for their custom. Nobility and rich merchants pay the courtesans large amounts of money to appear alongside them at events, and bravos are known to kill each other in their names.
Some Braavosi courtesans are famous, respected and wealthy and enjoy a kind of celebrity status as well as a certain kind of mystique. They are cultured and beautiful.
Would you sooner be a courtesan, and have songs sung of your beauty? Speak the word, and we will send you to the Black Pearl or the Daughter of the Dusk. You will sleep on rose petals and wear silken skirts that rustle when you walk, and great lords will beggar themselves for your maiden’s blood.

A Feast for Crows
When Cat is talking to some Westerosi sailors from the Brazen Monkey the youngest monkey, a red-haired boy with freckles no older than sixteen, asks her “What about them fancy whores the singers sing about?" His shipmates look at him and laugh. One of them says,
Seven hells, boy. Might be the captain could get hisself a courty-san, but only if he sold the bloody ship. That sort o’ cunt’s for lords and such, not for the likes o’ us. 
Cat tells them that she sold three cockles to the Black Pearl, she called to Cat as she was stepping off her barge.
As she pushes her barrow along the canals Cat sometimes glimpses one of them floating by, on her way to an evening with some lover.
