First off, i dont care what anybody dose behind closed doors but or me i would never do it, i am not into it but hey to reach his or hers own. Yet, i will give my reason in not being into it and forme this one is a good reason, you cant ask the animal if they want to have sex, therefore since you do know what the animal wants.. you might have to think of it as your forcing the animal in to something it dose not want to do .. and i am not into that idea...yes its a slipery slope logic but i will take it back if someone disproves me on it.
