No Filter: These Actors Were Really Getting Intimate On Film!
Paris 05:59: Théo & Hugo(2016)

Released in 2016, this French film cuts right to the chase in the first 18 minutes of the film. Two men meet at an adult club and engage in a nearly-20-minute unsimulated love scene. They later realize their intimacy had been unprotected and go to a hospital together for an HIV test before falling in love.
Variety‘s review of the movie said that the “biggest talking point will be the 18-minute hardcore gay orgy at the start, yet the film, conceived in real time, is above all a story about what happens when that bolt of lightning called love suddenly strikes.”
