Bullshit, Porn is one of the main causes. It reduces a woman to nothing more than her body. Thus, a man will assume that the greater the body, the greater the value of the woman. With this mindset, men not only expect their wives to look no less perfect than Miss September, they also do not appreciate a woman's most beautiful and precious qualities, since a centerfold display fails to highlight these. This drives men to look elsewhere in an impossible quest to satisfy their disordered appetites. After all, pornography fosters the false mentality that casual, uncommitted sex is the most fulfilling and enjoyable. Who does not want to be fulfilled?
