Hoffman, who has been married to his second wife, Lisa Gottsegen, for 27 years, said that to love one person is not natural, reports FemaleFirst.
The 70-year-old actor stated, "There’s so much about marriage that’s unnatural. I don’t think it’s natural to be monogamous, to be as in love as you were the day before."
The star explained that in spite of his point of view, he has never been unfaithful to his wife. He added, "Does fidelity make sense? Yes. I don’t think you can substitute honesty in a relationship."
