In "Psychology Today", there's a useful comparison between the relationship dynamics of gay/ lesbian and heterosexual couples. The key difference? On the positive side, the gays are more honest with each other: for example, by talking more frankly about their sexual interests, and their expectations about monogamy. On the negative side, gay couples - especially with men - just don't stay together as long. (The researchers don't mention it, but it could be of course, that the greater durability of heterosexual unions may have something to do with that little matter of marriage certificates, and even children. It is still too early for long-term studies of legally married same - sex couples, but there is some early research which does suggest that formal marriage does indeed contribute to married couples staying together longer than cohabiting relationships - just like the straights.)
Queer IQ: The Gay Couple's Advantage
Most lesbians don't fear rapacious women and gay men need not always soft-peddle their sexual predilections. On balance, gays and lesbians understand their partners' bodies and biases with a certainty that many a clueless "breeder" yearns for. "Homosexuality could be viewed in some respects as the triumph of the individual's mating intelligence over the gonads' evolutionary interests," argues Geoffrey Miller.
