Are you talking about this movie?
Secretary (2002) - IMDb
Never heard of it. But reading the plot it's also BDSM so what's the difference? I myself was surprised why 50 shades was successful and to think the author was a twilight fanfic writer!!!
LOOOOOOOOOL. So if you ask me, 50 shades IS a trashy romance book.
You Americans are just so sexually repressed which ironically is the complete opposite of my country's impression on you about sex.
