Well, when I was younger, like in my teens, I used to be very religious. I've always had a lust for animals since around the start of puberty (like many zoos do.) I used to be under the notion that sex with animals was automatically abuse/rape and an affront to God himself. I felt guilty that I was attracted to animals because when I was younger I equated Bestiality to equaling Rape, because I didn't know any better. Around 15-16 years of age is when I completely lost my faith in religion. By no longer believing myself to be born inherently in sin and amoral by the perception of God, I started having more faith in myself. I sought to know my own feelings, emotions, and current ignorance. I no longer saw myself as a sheep apart of a flock, but as an individual, while still imperfect, but an individual nonetheless.
Once this barrier had been lifted off of my shoulders I started to question why I thought of bestiality as akin to rape. So of my own volition I researched the topic of bestiality with a newly found secular worldview looking for non-biased resources. One of the first pieces of material I found was Peter Singer's Heavy Petting. Where he went into length about why our current view of bestiality comes from a completely illogical worldview. Namely of Judeo-Christian values. Piece by piece he logically tore down the erroneous moral objections to bestiality (if the animal appears to be enjoying themselves.) It really did open my eyes towards my own feelings towards the topic as a whole. Shortly thereafter I browsed the wiki article about zoophilia which I was surprised to find very informative and heavily informational. This led me to finding guides to safely have sex with animals, and guides to how to have a sexual relationship that is of mutual enjoyment.
Eventually I met some awesome people that were experienced with zoophilia and bestiality and with their friendship and mentorship I became the zoo I am today.
