JUST because the other person was zoo? No. But if there seemed to be true chemistry, alignment of life goals, and the potential for a strong relationship... it's possible.
I say this not because of the sex aspect, but more because keeping this desire secret takes its toll. Esp if my current partner was completely grossed out by it. Last year I dated someone who was zoo and it was just wonderful being able to talk about it, share intimacies, feel TRULY accepted. There wasn't a constant worry of being found out. It was very liberating. I'd love to find that again.
(ETA: this is said through the lens of a completely single gal. If I was truly in love my answer might be very differnt... lol)
