Hm, that’s at least one that seems to fit the description, I guess.
There are several more, most from foreign sources, none of the outright xxx advertised porn from the US.
Also some of their R rated are very very close to porn. I won’t give you the titles as you are not interested in these types of movies.
Netflix is a great source of older and hard to find movies for all tastes. My beef with them now is they won’t credit my account for a week. I have had to report them lost the past 4 weeks to get credit.
