Seeing your follow up posts, I do agree with you entirely. All sexual sin destroys spiritually, why the Scriptures speak so strongly against it, especially in the New Testament.
Jesus was very clear that what harmed a person was not eating non-kosher food, but such things as sexual immorality that were in their hearts.
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.
