Long shot at finding a film based off memory.
I saw a movie before 2006 (don't know specifics) and certain scenes have been stuck in my head ever since. There is a scene where the main female's (who I think was blond) ex-fiance/boyfriend kisses his own father and goes around with a paintbrush in his mouth. Another is when the guy shows the girl these start projections and they wind up having sex. Also there are father-daughter issues and the movie might be french, I saw it in France so Im not sure. THank you and I know this is not the most helpful description but it has been bugging me for ages.
