This is something I have been thinking about quite a bit lately. For years, I have been content with the explanation that God says it is wrong so it must be and whether we understand why or not is irrelevant. It's still the conclusion I will stick to until such a time as I accept an alternative. Lately however, I am beginning to want a better answer than that. Due to situations in my own life that have made love more real to me, I can't help but wonder how such a thing, even when expressed physically, can be wrong. I don't have a definite answer yet, but I am in the process of reevaluating my previous conclusions.
