From the Furry Fandom page on Wikipedia: "about 1.8% of persons self-identify as bisexual and 1.7% as homosexual" (this is outside the fandom) - compared to - "14–25% of the fandom members report homosexuality, 37–52% bisexuality, 28–51% heterosexuality, "
TLDR: gay and bi furries are a lot more common, so a lot will be gay porn.
This happened IRL when I was working, a full on furry in fursuit and all said to me "I wish you would shove a lemon up my ass hotboy." It was horrifying and I didn't know how to respond so I just walked away. I work in produce just FYI.

I can't beat that.
