Coming off as a lil' bit crazy there. Propaganda? Really? Okay, let's just ignore 90% of the established werewolf mythos from earlier movies, television and books so we can romanticize it.
Oh wait, someone
did do that a few times, in Twilight and the god awful mess that Blood&Chocolate became on screen. Now the book version of Blood&Chocolate is
exactly what you're actually talking about,
but even then they had painful transformations to an extent. Remember when she tried to fight her change, it became agonizing in that book. The rest of the time it was basically a full body orgasm though. In the movie it was magical poof TFs with no logical way of dealing with clothing. I would rather watch Bitten's poorly written story 100 times than look at the mess Blood&Chocolate turned into ever again. Neither story translated well to video, but both books were excellent in their original form. The issue is perhaps that both of those video productions had to water down the transformations, but with Blood&Chocolate there wasn't much left after it was diluted. They weren't going to have her get sexually aroused as she changed in the movie like in the book; so the poor man's version of that was the happy little run and jump TFs that took place in a split second and erased the person's clothing from existence randomly. Person takes off random articles of clothing then runs through the forest half naked and jumps and lands and is a wolf in midair after a magical flash of light, all the clothes they had on at the time are gone and when they change back.... the clothes stay gone for no reason. People taking their shirts off before they change only to have their pants vaporized by magic. It was the dumbest thing I'd ever seen up until that point. It's not what happened in the book at all. And that mess of a movie taught me something, Hollywood does
not want anything to do with the 'orgasmic tf'.
That was a bit of a rant, sorry.

^ Example of the problem Blood&Chocolate has with it's TFs. If we wrote scenes like that into stories around here, even
we wouldn't read them. Seems the choices are either painful or poof as far as Hollywood is concerned, pleasure is not likely something we'll find on the screen when we watch a TF scene. There are a few rare cases, but not from anything mainstream or recent. I'm up for pleasurable TFs too, but television isn't.
