I only reached that conclusion because a great deal of the time (not always but often) I'll start reading an "In progress" furry Comic that the artist claimed would be a Gay comic, then out of nowhere a Futa or hetero sex scene pops in towards the end, rendering the comic Bisexual rather than actually Gay
there's also one artist who USED to draw exclusively gay comics, then started drawing Bi ones, and is now (from the looks of it) a really weird Homophobe who still draws Bi comics but throws in weird morals about Straight sex being better and more normal than Gay sex....basically he's just a lunatic
