Trid, I don't think that's a fair statement. I think there are legitimate questions to be asked about acts appropriate to express the love of one human being for another, but I don't think we can automatically assume heterosexual acts are all "ordered" and homosexual acts "disordered." I don't think many couples of any orientation engage in sex while saying to themselves "I'm doing this to build the kingdom of God."
Well, maybe in Great Britain....:)
