I just watched the weird teen film Zerophilia (again). It's weird because it's about transgender issues, but it's a romantic comedy, and it's also kind of homophobic in its subtext (in a teen-fears, "girl-on-girl is hot but guy-on-guy is gross" kind of way), which is a real shame. Its premise is that some people in the world have an extra Z chromosome, and once it gets activated, they switch genders (anatomically speaking) when they have an orgasm. I found it unexpectedly moving, but at the same time (as I'm pretty bi) annoying. It's worth a watch as a coming to terms with yourself sort of story, even with the dodgy attitudes in some of it.
