@YummyTummySketties:
you might've also heard people quote/discuss the FurScience stats, which also had questions about orientation.

I've seen people use these as if they're representative of the entire fandom population, but it needs to be recognized that this wasn't a random sample of the entire community. rather they were mostly attendants of a few furry conventions who were comfortable answering a survey.

I don't think it's all that surprising that ~10-20% of con attendance is straight, since, while the furry fandom is pretty gay, furry conventions are, like, mega gay.
