From the introduction of a book "Dearest pet" by Midas Dekker.

"People love animals. A stroke here, a hug there, cuddling their nose up the animal's fur, almost to the jealousness of others. Dogs are caressed more than humans. But not as far as that sole spot, somewhere at the back. That spot is untouched. As noble as animals lovers are regarded, sex with animals is taboo. People that cross that line are subject of disrespect."

"Although it is not done, it does happen: sex with animals, the utmost consequence of love making, make love with. On the farm, in the barn, in the whore house and at home, but in most cases in our head. Our imagination is our best sexual organ."
Although "zoofilia" is a word often searched on our site, we have no relation with bestiality. Animal Freedom also means that humans are restricted to limit their sexual drives to other humans that have a choice.
When animals are free to live their own way they don't desire sex with humans. What humans do in their head or in the vicinity of animals, it is up to them.
