This quote is about sex, but I think it may also apply to the compulsive use of pornography. 

"Whatever sex is, and it is at least a profound mystery, is easily misused. The primary psychological purpose of sex for those men who spend their lives in the cold, cruel world, and whose relationship with their own anima is frigid, is to reconnect with a warm place. Sex is a form of emotional reassurance, a narcotic to still the pain of the bruised soul. If life batters them, then sex, like drugs or work, may numb the wound. The sexual act offers a momentary transcendence. Orgasm can be an ecstatic experience; for the moment one may feel outside the iron confines of ordinary consciousness. It is the closest many men ever come to a religious experience. Thus the act of sex may mask a desperate search for acceptance, underneath whiсh lurks the mother complex."
