Don't think is due to low marriage rate in Singapore, just exotic hobbies of these men. Anyway, never mention where is the location. Looks like security guards and police need to be more busy now onwards. :bsmilie:
Don't think a public toilet is considered a private place by the law. And it isn't likely a gay thing.
There was a case several years ago of a hetero couple getting into trouble screwing around in a car parked in a private condo (think the lady was a resident). One of the other residents called the cops. I suppose it comes under the same law.
