I'll add my two cents from a slightly different perspective. I have always been attracted only to women, and I am pretty sure that I want to be with my wife no matter what I do about my GD. In a way, that stopped me from understanding my GD until very recently.
Coming to what the media and entertainment world tells us, I've tried to look at love songs, romantic movies etc from the hetero perspective but could never get over the feeling that I was just pretending to like them. If I ever liked any of them, it had to be for some other reason, some theme which was rebellious, psychedelic, historical, political, sci-fi, fantasy, something else which had to make it unreal for me to like it. In fact, even the portrayal of lesbian relationships in songs or on screen is often from a hetero perspective and makes it unlikeable for me.
So I just don't care about what these songs and movies tell us. I am what I am, and if there are very few others like me, so be it. Media, entertainment, advertising etc is all driven towards the larger numbers, but that doesn't mean I have to be like them.
