There was a study on "coming out of the closet" to one's family in Asian countries. The funny thing is, nobody is actually coming out of the closet. The closet gets bigger so those people can come inside. HAHAHAHA. In other words, all your relatives would like to keep your homosexuality a secret.
I don't think Asian countries are any more open to homosexuality than others, but there is one thing that comes to mind.... Vietnamese people are generally accepting or at least understanding towards gay men (acceptance for being born that way), but they view lesbians as sick/mentally afflicted women. I think something similar like that happens in the Philippines, too.
