It seems the media doesn't see Bisexuals, only Gay or Straight. If you've been following the politcs on this side of the pond you'd see that two contenders for a politcal party leadership have been labeled gay, even though they are married on one case and the other stated he's had affairs with both. It's almost as if the media assumes that if you have sex with both Men and Women, then you are simply covering your homosexuality by having straight flings. There's no inbetween as they have to pigeon hole everything into certain catergories, hence Brokeback Mountain gets labled "that Gay Cowboy flick".
