Some Christians have a negative attitude toward sex. It may have come from a distorted sex education, an unfortunate sexual experience as a child, or sexual involvement as a teenager that brought disappointment and guilt. The origin is relatively unimportant. The important thing is to understand that we choose our attitudes.
The first step in overcoming a negative attitude is exposure to the truth. The truth about sex is that within marriage it is God ordained and designed to bring mutual pleasure. As in all of life we are called to live by the truth. We admit our negative attitudes and feelings, but we don’t serve them. With the help of God we live according to His revealed truth.
