Training. Personal development. Updating. Formation. Call it what you want. Everyone today sees the need for ongoing help in professional life. Why should sex be any different? That is, why should married men and women not receive ongoing help to make their sex lives more fruitful, fulfilling and fascinating? And faithful? Sex serves marriage. Marriage serves family. Family serves society. A married man is called to be his wife's lover. A married woman is called to be her husband's lover. This is why Sex-Love in Christian Marriage is an important book.
