Swingers swap sex partners in prudish Singapore

SINGAPORE (Reuters) - Every two months, dozens of couples meet in a pub in Singapore, have drinks, mingle, and then decide whether they want to sleep with one another.

In Sydney or Seattle nobody would bat an eyelid, but the couples are part of a thriving underground swinging scene that is an anomaly for a country where oral sex is illegal and Playboy magazine is banned.

There are at least 10 swingers clubs in Singapore, most of them private, some of them online. With more than 6,000 members, the Web-based United SG Swingers is one of the biggest.

“There are a lot more people that are open to the idea. It’s so widespread now,” said a 42-year-old Singaporean company executive who only wanted to be identified as Jack.

“Swinging is all about sex. It’s satisfying the urge to have casual sex and doing it with somebody you’re comfortable with,” said Jack, who has been swinging for 10 years.
