Yeah, I'd say so. Animals are mostly too dumb to know that sex causes children. So the only reason they do it is because it feels good. (Or they're being tricked or forced - human sexual morality doesn't always apply to animals.) Of course, attraction in many animal species works differently from humans. Pair-bonding is rare, and many animals only feel sexual desire at certain times of the month or year or when exposed to certain stimuli (eg the smell of a receptive female). What they like about a mating partner is very species-specific - in fact, it has to be to prevent them trying to mate with another species. For one random example, with most duck species, female ducks are genetically programmed to like certain patterns of coloration, which are present in their species of males. In contrast, the males' preference is determined by upbringing - they look for a female who looks like mom did. Hilarity and awkwardness ensue if you swap eggs between nests of different species, since the male will chase after his foster mom's species and ignore the females of his own species chasing after him.

I read that over 1500 species of animals display homosexual behaviors. And that some species are purely bisexual in nature. Yes, sometimes it can be a sign of dominance, or social status etc.. but some species bond and pair up with same sex partners. I'd consider that an attraction of sorts.
I think some of the higher IQ animals can be in love. Most "breed" but some smart animals like dolphins and chimps could conceivably love another of their kind. I won't deny the possibility of it. Love is odd.
The only problem is that some species have their own genders besides male/female since that is primarily a mammal thing.
