Heterosexual or Subtitle?

I noticed recently, as I was scrolling through the movie titles on Netflix, that a good portion of the non-heterosexual movies on there have subtitles. So I am wondering: are there a higher percentage of foreign films that include gay/lesbian stories?  Are other countries more liberal in terms of sexuality, as compared to the US? I just found it fascinating that if you're gay, you're pretty much forced to READ to enjoy a good romance movie. If I wasn't so visual, I'd stick solely to books!
