Check it out: my new post at the fantastic WriteSex site just went up. Here's a tease (for the rest you'll have to go to the site):
Only in erotica can the line “Come, Fido!” be problematic. Unlike some of the other Four Deadly Sins of erotica writing, bestiality is very hard to justify: with few exceptions, it’s not something that can be mistaken for something else, or lie in wait for anyone innocently trying to write about sex. This is unlike, for instance, discussing a first time sexual experience and have it accused of being pro- pedophilia. Bestiality is sex with anything living that’s not human: if it’s not living, then it’s a machine, and if it was once living, then it’s necrophilia.
A story that features—positively or negatively—anything to do with sex with animals is tough if not impossible to sell, though some people have accomplished it. However, there are some odd angles to the bestiality that a lot of people haven’t considered—both positive and negative.
On the negative side, I know a friend who had an erotic science fiction story soundly slammed by one editor because it featured sex with something non-human, technically bestiality—despite the fact that there is a long tradition of erotic science fiction, most recently culminating in the wonderful writing and publishing of Cecilia Tan and her Circlet Press (both very highly recommended). Erotic fantasy stories, too, sometimes get the “we don’t want bestiality” rejection, though myth and legend are packed with sexy demons, mermaids, ghosts, etc. This doesn’t even get into the more classical sexy beasts such as Leda and her famous swan, or Zeus and other randy gods and demi-gods in their various animal forms.
