Permitting gay marriage will not lead Americans to stop thinking of marriage as a conjugal union. Quite the reverse: Gay marriage has come to be widely accepted because our society stopped thinking of marriage as a conjugal union decades ago.
Between five and six decades ago, to be precise. That's when the birth control pill — first made available to consumers for the treatment of menstrual disorders in 1957 and approved by the FDA for contraceptive use three years later — began to transform sexual relationships, and hence marriage, in the United States. Once pregnancy was decoupled from intercourse, pre-marital sex became far more common, which removed one powerful incentive to marry young (or marry at all). It likewise became far more common for newlyweds to give themselves an extended childless honeymoon (with some couples choosing never to have kids).
In all of these ways, and many more, the widespread availability of contraception transformed marriage from a conjugal union into a relationship based to a considerable degree on the emotional and sexual fulfillment of its members — with childrearing often, though not always, a part of the equation. And it is because same-sex couples are obviously just as capable as heterosexual couples of forming relationships based on emotional and sexual fulfillment that gay marriage has come to be accepted so widely and so quickly in our culture. (If marriage were still considered a conjugal union, the idea of gay marriage could never have gained the support it currently enjoys. On the contrary, it would be considered ridiculous — as it remains today among members of religious groups that continue to affirm more traditional, conjugal views of marriage.)
