I can't be the only one getting tired of the constant ego pandering romances. It's a bit silly that in every adventure a main character has to come across 3 or 4 people who want to sleep with him. Avoiding gay relationships isn't simply about denying choices, but it's also statistically sound! In my 25... or is it 26, fudge I need to look at a calander, years I've only met one gay guy who wanted to sleep with me! (I think he was drunk, and creepy, but it was my fault for going to that particular bar) It's not that common of an occurance.
It's kind of like all those old kiddy cartoons like the Extreme Ghostbusters where there has to be an african american, an asian or hispanic, a woman, and someone in a wheelchair. Only now people are demanding it for their sex fantasies.
I demand cross-racial romances! I want a black woman, an asian, a hispanic, and a nice Russian woman (love the accent, rowr). And all at the same time! And a romance with a parapalegic, because it's time to demonstrate the socially acceptable nature of the handicapable! It's time to rebel and break down the walls of conformity!
PS: You should watch Torchwood. Davies made it a point for the first season to feature every major character in a same sex encounter. The characters don't draw gender lines in that regard. Especially Jack. He'll sleep with anything, "so long as it's beautiful."
