yiff = fox sex. REAL fox sex sex = HUMAN sex. furries = humans who like animals, maybe even go as far as to fuck them which = beastiality. beastiality = wrong, creepy, and should be ruled with a death sentence. "Furries" who have sex with other "Furries" = HAVING SEX. IT'SNOTYIFF. IT'S SEX. so again, furries, y u so stupid?
