extramarital sex without the consent of the married participant's spouse
- I'll match my private wife against any man's.

- Adultery is a meanness and a stealing, a taking away from someone what should be theirs, a great selfishness, and surrounded and guarded by lies lest it should be found out. And out of meanness and selfishness and lying flow love and joy and peace beyond anything that can be imagined.
- Adultery is the application of democracy to love.
