1 Corinthians 7:1-3

New International Version - UK

Concerning married life

7 Now for the matters you wrote about: ‘It is good for a man not to have sexual relations with a woman.’ ² But since sexual immorality is occurring, each man should have sexual relations with his own wife, and each woman with her own husband. ³ The husband should fulfil his marital duty to his wife, and likewise the wife to her husband.
