Couples who use NFP have sex less often than couples who use contraception.
Frequency of sexual intercourse is based on a couple's intention and desire, not on the family planning method.
NFP couples have sex as much as other married couples. They just have it on a different schedule according to whether they wish to avoid pregnancy or not. When spacing births, they would abstain from sexual intercourse during the fertile time of the woman's menstrual cycle. Keeping in mind that every woman is unique and every cycle is unique, the days of sexual abstinence will vary. But it's important to ask if the "frequency" of sexual intercourse is the right measure of fulfillment in a marital relationship. Most married couples would say that it is more important for their sexual relationship to reflect the quality of their marriage, that is, healthy, loving, intimate and respectful. NFP can be a great help to couples who are interested in building a strong marriage because NFP supports the gift of one's spouse, the gift of life and God's design for married love!
