What harm is there if I dress up like a maid and seduce the man-of-the-house? Or when Mm gives me a peck before going up on stage for him to "keep that thought" ? That is 'spice' between the two of us.
When you introduce porn into your life, you are allowing someone else into the marital bed with you. The intimacy
between two people has been violated.
"Pornography feeds lust of the eyes and lust of the flesh, which are never satisfied. It leaves the viewer craving more and more in order to achieve the same "sexual high." It easily enslaves people to their own cravings and opens the door to other forms of evil, like anger, abuse, violence, hatred, lying, envy, compulsiveness and selfishness. The power behind porn is revealed when the porn addict tries to stop their habit - its virtually impossible without help."
