My first fandom that strictly has two female characters is Star Trek: TOS, and the two female character don't have much interaction between them. Then my next fandom Stargate: Atlantis initially for a period of time has two main female characters. Condequently for a long time I don't read much femslash. It's only when SGA introduces more female characters that my interest in femslash is aroused. My current fandom is Marvel comics fandom, which despite its many faults, has a large cast of female characters so I no long come across this problem.
