It is true that to avoid pregnancy, couples need to abstain from sexual intercourse during the fertile phase of the woman’s cycle. This is a fundamental aspect of all natural methods. However, studies comparing frequency of intercourse between those practicing natural methods and those using artificial methods have found little difference. And couples using natural methods report significantly higher levels of satisfaction. Most loving couples, however, are surprised to find that voluntary postponement of intercourse can promote greater communication, mutual respect and cooperation, sexual fulfillment, and a stronger total relationship.
