Hey guys, I remember seeing this erothic thriller a while back. I don’t remember much, just that the female protagonist was blonde and that she started dating this guy. The movie involved a lot of nudity and sex. One particulat scene I remember is the protagonist seeing a redheaded woman in the shower and then the man said that she was an expensive prostitute and he made the two of them make out.
maybe “9½ Weeks” or one of its sequels?
