Nope, it's practically non-existent. Unless you know where to look. I live in Jakarta, Indonesia. The LGBT community are having a hard time around here sadly. It's a Muslim-majority country, so even straight PDA is pretty rare. In the more Chinese communities, or flashy malls it's a tiny bit evident (straight PDA), but nothing more than the usual hand-holding and hugs.
According to the "law" though, couples aren't supposed to hold hands unless they are married. Although this is probably hardly enforced at all, not many kids are keen to test it out. They have teenage sex and pregnancies like anywhere else in the world, just most like to turn a blind eye to it, which makes it even more tricky for education on things like homosexuality/transgenderism (sorry if that's not a word), or even things like birth control and STD's.
