"pornography and masturbation represent the destruction of the symbolic and nuptial meaning of the human body...God gives all men and women erotic energy. We call it the sex drive. This is good and it forms part of that attraction between men and women, which itself forms part of the nuptial meaning of the body. Sexual energy, therefore, needs to find its outlet in love, not lust...In masturbation that erotic energy is turned in on oneself...Masturbation, therefore, is a symbol, not of love, but of loneliness." - John Paul II, Theology of the Body
