XD so according to my new Furry friend Sheogorath, foxes tend to be bisexual or homosexual? He said he was surprised to find a straight male fox in the fandom! I don't know if he's right or not, but if he is I guess I learned something new today
From what I understand, since foxes are possibly the most common fursona (with the possible exception of wolves), you have the largest sample size there. Since heterosexuality is the most common sexuality, then logically a majority of foxes are going to be heterosexual.
But yeah, a lot of artists like to draw gay foxes.
