The tricky thing about any sex culture is that individual people have different ways defining the boundaries of that culture. For example, if I say that I beat off to anthropomorphic (furry) figures on occasion, I can illicit all sorts of responses from different people. Some people will write me off as furry despite the fact that I don't have a "fursona", fursuit, furry avatar/spray or any other trait associated with furrys. Others will say that I'm a semi-furry in that I have a trait that identifies me a furry but this trait alone doesn't allow me to completely associate with the furry culture by default. Others will say that I am not a furry and simply curious about a certain sexual genre. So really it's not really a question of "What is a furry?" but rather a question of "What do you have to do be classified as a furry by other people?"
