The answer
In general, there should be a period where the married couple refrains from sexual activity during fasting days. The length of this time during extended fasts should be determined and agreed upon by the couple so that it is fair and reasonable for both."Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer; and come together again so that Satan does not tempt you because of your lack of self-control" (1 Corinthians 7:5).
