SINGAPORE - From the outside, they look unremarkable.
To the passer-by, the spaces may well be offices as their exteriors are muted. No neon lights here.
The doors of their main entrances are made of frosted glass, making it impossible for passers-by to sneak a peek.
But behind these closed doors, which admit only men who are registered patrons, is a venue for gay men to meet and hook up.
Men-only clubs made headlines last week when a coroner's inquiry was heard in court. A 49-year-old man was found dead on the premises of Club One Seven in Upper Circular Road in November last year.
The man had been found naked, hanging from a metal chain.
In court, the possibilities of auto-erotic asphyxiation was mentioned, as was suicide.
It is believed that there are at least seven men-only clubs here. They advertise gym and health facilities and even cafes where one could hang out.
They are known as "saunas" in the gay community.
