Sex workers are “female, male and transgender adults and young people who receive money or goods in exchange for sexual services, either regularly or occasionally”. There has been little research done on sex workers in Malaysia, and sex workers exist underground due to a prohibitive legal environment as well as stigma and discrimination within the society. Sex work venues range from the streets to entertainment establishments such as fitness clubs and hairdressing salons. Many people who exchange sex for money or goods do not self identify as sex workers, and neither do they seek nor have access to HIV prevention, treatment, care and support advice or services for sex workers.
