1 Corinthians 7
3Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
4The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.
5Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
Yes, but this passage does not mean that each spouse is bound, under the penalty of mortal sin, to agree to every request of the other to have relations. That would be ridiculous. And it is not what the Church teaches.
