It's sort of a damning fact about fandom, though, that when I went looking for fic I found much more m/m than I did f/f, despite fact that the focal relationships on the show are either between a man and a woman or two women, and in general the male characters aren't actually that close to one another and don't have a lot of interactive screentime (particularly before the introduction of Sweets). There was the relationship between Zack and Hodgins, and that was kind of it for the first three seasons. And yet, so much m/m.
