A lot more places than just those two countries, I suspect.
In fact, it seems to be a common attitude in Asia, that teen girls (moreso than boys) will often "try out" relationships with each other, pretty much for the same reasons as above. There's a lot of varying degrees of this you can see in media coming out of those countries (Japan and Korea come to mind).
Of course this makes it more difficult for *actual* lesbians to come out, since their parents dismiss it as just being a temporary phase.
