I don't think same-sex marriage will happen in China in near future either.
People tend to ignore the gays in most cases.
Maybe they will talk behind your back.
But you won't be bullied because of this.
Actually, in history, gay sex was seen as normal as heterosexual sex.
In our most famous literature, Dream of the Red Chamber, there're plenty of same sex descriptions.
Some are romantic, some are ridiculous, some are purely carnal.
It's not a big deal.
In Chinese history, there's no such period that gay folks were killed just because of their sexuality. This is quite different from Europe.
Maybe it's because of the lack of a steadfast faith of God or Budda, or anything there.
China is always a secular nation.
