God calls it shameful lusts:
(Rom 1:26-27) 26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another.

Correction:
Paul calls it shameful lust.
Assuming Paul even really wrote that particular letter, and it wasn't someone else writing in Paul's name so people would pay attention.
So, assuming Paul wrote it, and assuming that in this particular case Paul had an ear to the Almighty (given that in several other instances he admits to writing his personal opinion rather than relying on whatever divine revelation he had hitherto relied on), you honestly believe that a man from the 0000s or 0100s A.D. could have had any notion of a world in which people married for something other than procreation or property?
A world in which women are NOT generally treated as chattel, in which information is created and broadcast almost at the speed of light (another concept he had no notion of), in which humans fly through the air in vacuum-sealed metal tubes fueled by liquid dinosaurs (what are those, Paul?), and in which another set of vacuum-sealed metal tubes fueled by liquid AIR have enabled us to LEAVE THE PLANET?
Really? You really think that?
And you honestly believe that a couple who has stayed committed to one another for longer than you have been alive, including through a time in which either or both of them could have been arrested for the act of staying committed to one another, are only acting out of "shameful lust"?
And you wonder why yours is a species which grows further toward extinction with each more-enlightened generation.
