Sex has high stakes, including exploitation, disease, illegitimacy, incest, jealousy, spousal abuse, cuckoldry, desertion, feuding, child abuse, and rape. These hazards have been around for a long time and have left their mark on our customs and our emotions. Thoughts about sex are likely to be fraught, and not entertained lightly. Words for sex can be even touchier, because they not only evoke the charged thoughts but implicate a sharing of those thoughts between two people. The thoughts, moreover, are shared \u201con the record,\u201d each party knowing that the other knows that he or she has been thinking about the sex under discussion, which embroils the dialogue in an extra layer of intrigue.<\/p>\n\n\n\n
Evolutionary psychology has laid out the conflicts of interest that are inherent to human sexuality, and some of these conflicts play themselves out in the linguistic arena. Plain speaking about sex conveys an attitude that sex is a casual matter, like tennis or philately, and so it may seem to the partners at the time. But the long term implications may be more keenly felt by a wider circle of interested parties. Parents and other senior kin may be concerned with the thwarting of their own plans for the family lineage, and the community may take an interest in the illegitimate children appearing in their midst, and in the posturing and competition, sometimes violent, that can accompany sexual freedom. The ideal of sex as a sacred communion between a monogamous couple may be old-fashioned and even unrealistic, but it sure is convenient for the community over casual talk about sex.<\/p>\n\n\n\n
Even keener than the sexual conflicts between young and old and between indivisual and society is the conflict between men and women.we are mammals, and have inherited the asymmetry that runs through that class: in every act of reproduction, females are committed to long stretches of pregnancy and lactation, while males can get away with a few minutes of copulation. A male can have more progeny if he mates with many females, whereas a female will not have more progeny if she mates with many males \u2013 though her offspring will do better if she has chosen a mate who is willing to invets in hem or can endow them with good genes. Not surprisingly, in all cultures men pursue sex more eagerly, are more willing to have casual sex, and are more likely to seduce, deceive, or coerce to get sex. All things being equal, casual sex works to the advantage of men, genetically and emotionally. We might expect casual talk about sex to show the same asymmetry, and so it does. Men swear more, on average, and many taboo sexual terms are felt to be especially demeaning to women \u2013 hence the old prohibition of swearing \u201cin mixed company.\u201d <\/p>\n\n\n\n
