You don't need to fit anyone else's mold for how you need to be. Human or non-human, if they are a willing partner and they are unharmed, what's the problem?
If you want a human partner, work towards that end. If you want a non-human partner, work towards that end. These aren't mutually exclusive options with no turning back. You can try to make, for example, a human relationship work. I'm a zoo exclusive, but when I was younger I tried to make human relationships work. They don't seem to work for me, but they work for others and that's OK. If they did work for me, that would be OK too, it's my life and so long as I'm not harming others there's nothing to feel bad about. If you are attracted to non-humans, there's nothing wrong with pursuing that so long as you are taking good care of them and providing them with a nurturing environement. If you happen to be one of those people who have interests in both areas, it's a bit more complicated, but certainly possible to find a viable solution where you aren't deceiving your partner.
If you try humans and you find it unfullfilling, perhaps explore a non-human partner. I find my relationships with canines very fulfilling, but others do not, follow your own feelings and so long as you are providing them with a loving and nurturing home I don't see a problem with it. If you do and find you are unsatisfied with a non-human, you still have a companion who will still be all of those things, but perhaps no longer a lover.
I personally tend to think that if you feel a human option might work that you try that first as there are a lot less complications, but whatever you choose, take care to find a partner who matches your lifestyle and interests, human or non-human.
