Fair enough :-).
Jesus seemed concerned when the natural desire in marriage, which may or may not have an element of lust in it, was directed outside the marriage. To do that in one's heart was considered sinful.
Beyond that, I don't know how anybody can really judge it objectively as it is such a subjective thing.
Unbridled lust or persons incapable of healthy emotional attachment and fulfillment are not a desirable thing imo and bring much heartache to individuals and society.
I do think people having a spiritual bond in their relationship are better off. The others are missing something important, but that is their problem and they have to deal with it.
