Personally I’m split between 2 types. A dull movie and a sexual/romantic movie. I think a boring, but not too bland, movie would work here because she’ll be looking for a distraction from the movie. On the other hand something sexual/romantic could turn her on.

But if the movie is too interesting then my attempts at escalation will distract her from the movie. Having said that, would a horror movie work? Or something else I haven’t considered?
