 If a new study came out saying that if you sleep with your girlfriend then you're half as likely to get cancer, that does not give us license to go against God's commands. Yes, God designed us as sexual beings, but real men can control their sexual urges. Only a man child says he can't help but watch porn and masturbate. But a man seeking the Lord needs to learn to control his sexual urges. Put to death therefore, what is earthly in you? Sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. The guilt and shame we feel after the act comes from our conscience. However, when Jesus died on the cross, he bore the weight of all our guilt and shame on himself. Trust in Jesus and receive freedom and forgiveness today.
