Clients of prostitutes are sometimes known as johns or tricks in North America and punters in the British Isles.
A variety of terms are used for those who engage in prostitution, some of which distinguish between different types of prostitution or imply a value judgment about them.
Common alternatives for prostitute include escort and whore; however, not all professional escorts are prostitutes.
The word "prostitution" can also be used metaphorically to mean debasing oneself or working towards an unworthy cause or "selling out". For the sake of the longed alliance with imperialist democracies [Stalin] has brought the Comintern to the last stages of political prostitution." Besides targeting political figures, the term is used in relation to organizations and even small countries, which "have no choice but to sell themselves", because their voice in world affairs is insignificant.
In this sense, "prostituting oneself" or "whoring oneself" the services or acts performed are typically not sexual. In 2007, a Russian caricature depicted the Baltic states as three "ladies of the night", "vying for the attentions of Uncle Sam, since the Russian client has run out of money".
Prostitution is one branch of the sex industry, along with pornography, stripping, and erotic dancing.
