Anything that raises any internal honesty about gay life is inherently suspect.
Some of this is unavailable to the male-female union: there is more likely to be greater understanding of the need for extramarital outlets between two men than between a man and a woman; and again, the lack of children gives gay couples greater freedom. Their failures entail fewer consequences for others. But something of the gay's relationship's necessary honesty, its flexibility, and its equality could undoubtedly help strengthen and inform many heterosexual bonds.
I think you earn your reputation for honesty and integrity literally hour-by-hour, and taste for that matter.
