Pornography is a medical and public health problem because so much of it teaches false, misleading, and even dangerous information about human sexuality. A person who learned about human sexuality in the “adults only” pornography outlets of America would be a person who had never conceived of a man and woman marrying or even falling in love before having intercourse, who had never conceived of two people making love in privacy without guilt or fear of discovery, who had never conceived of tender foreplay, who had never conceived of vaginal intercourse with ejaculation during intromission, and who had never conceived of procreation as a purpose of sexual union. Instead, such a person would be one who had learned that sex at home meant sex with one’s children, stepchildren, parents, stepparents, siblings, cousins, nephews, nieces, aunts, uncles, and pets, and with neighbors, milkmen, plumbers, salesmen, burglars, and peepers, who had learned that people take off their clothes and have sex within the first five minutes of meeting one another, who had learned to misjudge the percentage of women who prepare for sex by shaving their pubic hair, having their breasts, buttocks, or legs tattooed, having their nipples or labia pierced, or donning leather, latex, rubber, or child-like costumes, who had learned to misjudge the proportion of men who prepare for sex by having their genitals or nipples pierced, wearing women’s clothing, or growing breasts, who had learned that about one out of every five sexual encounters involves spanking, whipping, fighting, wrestling, tying, chaining, gagging, or torture, who had learned that more than one in ten sexual acts involves a party of more than two, who had learned that the purpose of ejaculation is that of soiling the mouths, faces, breasts, abdomens, backs, and food at which it is always aimed, who had learned that body cavities were designed for the insertion of foreign objects, who had learned that the anus was a genital to be licked and penetrated, who had learned that urine and excrement are erotic materials, who had learned that the instruments of sex are chemicals, handcuffs, gags, hoods, restraints, harnesses, police badges, knives, guns, whips, paddles, toilets, diapers, enema bags, inflatable rubber women, and disembodied vaginas, breasts, and penises, and who had learned that except with the children, where secrecy was required, photographers and cameras were supposed to be present to capture the action so that it could be spread abroad.
