Prostitution is the act of providing sexual services to another person in return for payment. The best known frequenter of whores is Tyrion Lannister. Amongst whores, there are many hierarchies. Some cater to highly exclusive clientele, make a good enough living and may to a certain extent pick and choose their clientele, while others take who they can get and do whatever they have to in order to survive, often living miserable lives. In Essos many whores are enslaved.
Whores are normally on the bottom rung of the societal ladder, even the wealthier ones, and are looked down upon by most people because of their trade. It is considered dishonorable for a nobleman to openly frequent whores and brothels. Despite these attitudes, Westeros teems with brothels and whores. In Dorne attitudes towards prostitution are more relaxed.
Some brothels in Westeros cater to more exclusive clientele. In contrast, the Lazy Eel is renowned for offering some of the oldest whores in White Harbor. A certain kind of whore, referred to as a camp follower follows armies and sellsword companies.
