I've never really had ''trouble'' with my sexuality and never really thought what I seeked for was wrong.
I never cared about being ''normal'' either, as I was never considered ''normal'' in the first place by anyone ever.
I only hate being a zoophile for some certain reasons. I'd say problems with body size, the law, how other zoophiles are and that my animal doesn't understand romance bother me the most.
...As for anything else, there's actually good sides to it.
They may not understand romance, but they certainly love you more than a human would. Under your care, a lot of animals literally need love to be happy.
That said, they will never betray you or harm you in any way. If you're good for them, they're good for you.
Animals also just live with you. For me it feels good to know we'll be together so often.
That definitely shows, as sometimes she even gets too much attention from me and because I'm constantly with her.
I'm quite happy that I'm not attracted to humans, but that may mostly be my misanthropy speaking. I've looked in your post history and I can say I would feel the same way if I was attracted to humans.
There's many more reasons for this, but I don't think you're searching for those.
Here's one thing that may work but something you shouldn't rely on: Wait it out.
There's also something else you need to know: All of this only works if you want to change.
Why do you care about being normal? So what if others are dissapointed?
That's dumb, because you shouldn't let others control your lives. Are you going to adjust yourself to everyone you meet?
As for the whole ''morally wrong'' thing, how is zoophilia wrong to you?
I'm going to take a big assumption and say you think bestiality = rape as that's the most common one and I couldn't imagine something else.
Let me remind you that in order for sex not to be rape, they must know what sex means. They're sexually mature adults, so they do know what sex is.
Animals can show their will to have sex with their body language. I say watch a documentary and you'd know what it really means and how they do it.
I'll also leave something for you to think about: Where do you draw the line?
Do you think it's wrong for a dog to have sex with a wolf? (Same family, can reproduce together.)
Do you think it's wrong for a dog to have sex with a fox? (Same family, can't reproduce together.)
Do you think it's wrong for a dog to have sex with a cat? (Different family, can't reproduce together.)
Do you think it's wrong for a dog to have sex with a monkey? (Different family, can't reproduce together.)
And lastly... Do you think it's wrong for a dog to have sex with human, then?
At what point do you think it's wrong and why?
