Pornography exploits and cheapens the most intimate of human relations and one of God’s greatest blessings for marriage. It perverts and obfuscates the purpose of sex — the creation of new life. It also damages relationships – see here, here and here. Oh yeah, the girls performing in porn are most often repeating in front of the cameras the abuse they suffered as children and later as prostitutes. See here. Finally, children know and pick up quite a bit about what their parents are really about. It’s my belief that children are prone to follow in the path of a parent’s “secret” sin because it really was not that secret. No doubt, porn harms.
