So, I've found an image that has an anthro and a feral in the same image with sexy bits plainly visible, and sexual intent obvious...but no actual sex is occurring, yet. Does this still count, given they're doing something sexy, or does it NOT count because no actual sex?

Seeing the image in question might help people determine.

Well, I meant more in general than just for that one image, but I suppose I can show it for example purposes at least...

The wiki mentions sexual activity, but not necessarily actual sex. This is reaffirmed by the fact that bestiality does not imply sex. So yes, in general I would say that it does apply. Though, more specifically, I would say that anthro_on_feral would apply for that particular image, which would then imply bestiality - better to tag the more specific pairing and let implications handle the rest.
