I don't believe that someone's sexual preferences are an accident. Kinks can be influenced yes, however I believe innate lifestyles can't. I'm not going to get into whether zoophilia is a kink or a lifestyle. Before I came into accepting I can have feelings or lust for animals, I was previously turned on by furry characters growing up. Although, I don't believe that has any bearing on me finding animals attractive. I personally think my bisexuality feeds into my feelings a bit. To me, any consenting induvial with a pulse is good enough for me.
