Sexual greed, a selfish desire to solely satisfy sexual gratification, needs to be completely avoided. It will influence only lust, and lust destroys love, both love for another and love for God. Sexual immoral thoughts are likely to lead to immoral behavior, therefore preventing both is important. Even so, If you are treating sex more like an activity to satisfy urges instead of an expression of love, the sex within your marriage is still being driven by lust. In other words, marriage does not excuse lust. It is important, regardless of your status, to be self-disciplined and make lustful behavior and thoughts absent from your life.
(Ephesians 5:3-5) "Don't allow love to turn into lust, setting off a downhill slide into sexual immorality, filthy practices, or sexual greed. Among you there must not be even a hint of sexual immorality, or of any kind of impurity because these are improper for God's holy people. Nor should there be obscenity, foolish talk or coarse joking, which are out of place. For of this you can be sure: No immoral, impure or greedy person has any inheritance in the kingdom of Christ and of God."
