I had usually held the
opinion that bestiality is
wrong, not because the idea of
sex with another
species being somehow "
unnatural" or "
immoral", but because
animals can't give
consent, and therefore bestiality is by default
rape. However, after reading
How to have sex with a dolphin, I have realized that that is completely
untrue: if an animal
approaches you, or is in some other way allowed to choose to initiate the
sexual encounter or not, that could be perceived as consent, no?
Yes, sex with animals is icky. Yes, it's a good way to encourage interspecies transmission of diseases, especially when with primates. Yes, it's socially unacceptable. Yes, it's bizarre.
But is it wrong?
My general opinion has always been that all sex that other people have, as long as it is consensual, is something that's OK, whether it appeals to me or not. Given this principle, it appears that whenever an animal consents—as many actually are able to do—to have sex with a human, is completely acceptable.
