Based on Ben Affleck's complicated dating history, the actor seemingly has a hard time maintaining romantic relationships. His '90s romance with Gwyneth Paltrow, and why it ultimately ended, clues us into Affleck's apparent boyfriend habits.

As outlined in a new biography about Gwyneth Paltrow, the actress’s sex life with former boyfriend Ben Affleck was apparently hot and heavy—so much so that, according to the book’s author Amy Odell, they couldn’t keep their hands off of one another, even on set.

FYI, Gwyneth opened up about her relationship with Ben during Call Her Daddy saying that both he and Brad Pitt were "good kissers," and that when it came to who was better in bed, "That is really hard. Because Brad was like the sort of major chemistry, love of your life, kind [of hookup]. And then Ben was, like, technically excellent."
