Julian Barnes. Metroland (№ 124378)

marriage, life, fashion, sex do not believe in these new postulates. Before it was: not ***is on the side, because you'll be unhappy, and you'll catch syphilis, and infect his wife, and you have children-morons, like those of Strindberg or Ibsen, or anyone out there, can't remember. Now that sounds: ***is on the side, otherwise you'll die of boredom, and he becomes tedious and boring, and don't meet new, interesting people, and in the end becomes impotent with everyone but his beloved wife.
