Believe me, I've tried just about everything to come to terms with my zoophiliatic side.My suggestion is to do a lot of soul searching and not take a lot of time. I spent decades in turmoil going back and forth , each time walking away trying to convince myself that its just a fetish and wrong at that. I suggest that you don't drag out the process as all I feel I did was deny myself many good years of who I really am and what I really wanted in life.
This was how it was for me too, the attraction started so young at least to me now it kind feels like it has always been there so I never really had the time to feel guilty about it. It’s like feeling guilty about the fact that I have ten fingers.I started being attracted by dogs when i was very young so i never really felt guilt as I grew up like that but i always knew it wasn't something "normal" that i could share with my friends
