Chastity is one of the seven virtues and it is defined as refraining from deviant sexual conduct. Chastity is usually defined within the moral standards and guidelines of a culture, civilization or religion. The term is closely associated (and can be used interchangeably) with sexual abstinence, especially in the context of premarital and extramarital sex.
"Physical intimacy between husband and wife is a beautiful and sacred part of God's plan for His children. It is an expression of love within marriage and allows husband and wife to participate in the creation of life. God has commanded that this sacred power be expressed only between a man and a woman who are legally married. The law of chastity applies to both men and women. It includes strict abstinence from sexual relations before marriage and complete fidelity and loyalty to one's spouse after marriage.
This particular Virtue will help you if you need help holding on in this area. or indeed any other area where Virtue is needed not just in the bedroom outside of marriage.
