A man who does not regard himself as gay or bisexual, but who has sex with male clients for money, is sometimes called gay-for-pay, or trade. A more dated term for a man who dressed similarly to female sex workers and tried to pass as a woman is known as a fairy. Male clients, especially those who pick up prostitutes on the street or in bars, are sometimes called johns or tricks. Those working in prostitution, especially street prostitutes, sometimes refer to the act of prostitution as turning tricks.
