Also I don't see why people detest sex with animals. It's not that i condone it myself, but people are against it. I asked my friend recently what his problem was with it (the subject sorta came up), and he said it's sad for the animals, to which i replied they might actually want to (I dunno, a dog humping a leg is usually indication of that). After that he had NO argument.
Here's the argument. Penis size.
Depending on the animal involved, a human cock is either too small to be noticed, so the animal wouldn't be overly bothered, or too big and would cause severe internal damage. Human cocks are only designed to fit humans, not ducks or horses. Furthermore animals have different ways of doing things. A dog for instance will become familiar with another dog by sniffing it's butt. This doesn't work for humans, we have an entirely different social protocol.
Furthermore, in the dog example. Dogs don't actually have sex that way. That is merely an attempt to initiate sex. Dogs aren't exactly bright enough to tell what is and isn't a dog when they're horny, but humping is not the act of sex, it's the act of initiating sex. Just because a dog is humping doesn't mean it wants to have sex with your leg, it can be a sign of other things such as close affection, or playfulness.
Animals never really want to have sex with humans. They seldom ever want to have sex with anything that isn't close to their species (very few animals mate outside their species, and then only with similar animals such as lions and tigers, or donkeys and horses). Plus animals lack the ability to know quite whats going on to the same level humans do, and there's no way of definitively knowing if it's something they actually want, or, like in a lot of female animals cases, something that just happens. In nature, a lot of female animals pretty much just lie back and take it, they don't actively pursue it, but they let it happen, because that's how breeding works for them. The males do all the work, so they just sort of stand there and let them do what they have to. If it's in their nature to be complacent and not react when being mated with, how can you actually tell if they want it with their own species, much less a human?
