couple goes to a retreat and it ends up being an experiment on sexual activities, they make them wake up and do experiments/exercises that are related to sex. I thought it was Robert D Jr but I couldn’t locate it through his name. Even though it was probably made in the 90’s the film was based of around the 40’s? Not sure of the year it was filmed, early 2000’s.
