Midge Dector’s assertion in a National Review essay that “women are by nature monogamous†is easily disproved by studies showing the infidelity rates of young wives as approaching or surpassing those of husbands and of DNA studies showing that many children conceived in wedlock are not the biological offspring of the husband.
However, she is correct to note that lesbians tend to live in at least theoretically faithful unions (with a not inconsiderable amount of “cheatingâ€Â) while gay men are likely to incorporate provisions for outside sexual dalliances into their relationships even if long-term and committed. Perhaps the logical conclusion to be drawn, for anyone who places a premium on monogamy, is to permit women to marry each other but prohibit men from marrying other men. This would be compatible with conservative principles that can permit some things for one gender but not the other, as in the male-only Roman Catholic priesthood.
