Prostitution is tolerated in six designated districts, most notably Geylang, which ? not coincidentally ? also offers some of the cheapest lodging and best food in the city. The industry maintains a low profile (no go-go bars here) and is not a tourist attraction by any stretch of the word. Legally practising commercial sex workers are required to register with the authorities and attend special clinics for regular sexually transmitted disease screening. However, please be prudent and practice safe sex--although most sex workers will insist on it anyway.
Orchard Towers, on Orchard Road, has been famously summarized as "four floors of whores" and, despite occasional crackdowns by the authorities, continues to live up to its name. Beware that the prostitutes working here are usually not registered, so the risk of theft and STDs is significantly higher, and not a few of the "women" are actually transsexuals.
