After reading a lot of this thread, I thought I'd chime in with a lot
of stream-of-consciousness points, for good, ill, and weirdness:
----
Art, in my mind, consists not only of medium and message, but of
audience and artist as well. As the message created passes from the
artist through the medium, any attempt is limited by the artist's
limitations of professionalism and time. Since most TF artists and
storytellers (including myself) are not professionals, limitations
are bound to be common, and commonly noted as well. But most
importantly, if the audience per individual is not affected in the
way that the message was intended, then that's a failure. But if that
effect is not destructive, then that's acceptable.

To that effect, porn IS art, albeit one of the most base and morally
disturbing kinds, especially to you, if I understand you right.

Art is not only limited to an uplifting or empowering matter for the
soul, but it does appeal to the more visceral from time to time.
Among consenting and responsible adults, also acceptable.

A good amount of TF is "wank fodder", including much of my literary
work (as opposed to my art. Weird.) I have no problem with that,
mostly because I know the difference between what I do and what
others do, and I try to stay flexible in approach and aim with my
work. It helps me stay out of a rut (pun fully intended).
----
Anatomical correctness isn't necessary in art; sometimes the mind's
eye is more important than the correctness of the anatomy. Since
transformations are not only impractical, but incredibly awkward, not
to mention the spontaneous specialization of millions of cells and
the gain (or loss!) of nearly 100% of body mass or more in a matter
of seconds... I think a few anatomical details can be forgiven if it
makes the piece "work" in the viewer's imagination.
----
I have personally met Arania, and she's a decent enough sort. I think
a comment on her sexual experience is unfair, most likely uninformed,
and at the very least, it is an inappropriate insult to a person as a
whole in response to actions that you personally do not approve of.
----
As for myself, I agree with Liz Karn and others here who do accept
sexually charged transformation as erotic escapism and thrill as I
myself do. And the fact that there are females who enjoy this kind of
thing... gives me hope that I can find a companion who understands
me. Thanks, ladies!
----
My reasons for liking transformation have as much to do with my
personal inadequacies as they do with the wonderment and empowerment
of experiencing different kinds of life. Like galloping, for example;
that'd be awesome. Or smelling things with a wolf nose; my human
sense of smell is awful, even by human standards. This also applies
to freeing my inner desires by way of imagining myself or others as
dropping their inhibitions by simply not being quite human anymore,
and being empowered themselves by that fact. Porn? Maybe. But it can
be empowerment, harmless escapism, or self-therapy if handled with
care.
