Exactly what counts as porn and FFM what doesn't vary with the jurisdiction. Where I live, the law says porn is a depiction of "sexual organs in action" with a specification of how erect a penis must be to be considered "in action".

So most sex scenes in TV series and mainstream movies would technically not be porn. Not 'hard' porn, at least.

The boundaries for 'soft' porn are more blurry, and doesn't require much more than that it might potentially excite the viewer. Arguably, most sex scenes, fashion magazines and romance novels could be considered soft porn.
