Malaysia is a socially conservative society and 'out' behaviour is looked upon disapprovingly; we strongly suggest discretion. Homosexual acts between males are illegal and penalties technically include corporal punishment and long prison sentences, though these are rarely enforced. Homosexual acts between women can also include imprisonment.
In Brunei homosexuality is illegal and punishable by death. It's a good idea to keep a low profile if you're a visitor.
Homosexuality is not illegal in Indonesia, but 'out' behaviour is a very bad idea.
