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. Thus one may be referred to as a male escort, gigolo (implying female customers), rent boy, hustler (more common for those soliciting in public places), model, or masseur. Where prostitution is illegal or taboo, it is common for male prostitutes to use euphemisms which present their business as providing companionship, nude modeling or dancing, body massage, or some other acceptable fee-for-service arrangement. Some terms vary by clientele or method of business. The terms used for male prostitutes generally differ from those used for females.
