1 Corinthians 7:1-3

1 Corinthians 7:1-3 NLT

Now regarding the questions you asked in your letter. Yes, it is good to abstain from sexual relations. But because there is so much sexual immorality, each man should have his own wife, and each woman should have her own husband. The husband should fulfill his wife’s sexual needs, and the wife should fulfill her husband’s needs.
NLT: New Living Translation
