Wow - if dudes here take this as true then they are going to be in a world of misunderstanding and hurt! There are so many errors here on so many levels. I'll just say that this viewpoint obviously only comes from minds who believe we are mere animals and believe in the fake biological evolution darwin nonsense! Humans are much more than desire - we are thinkers, we have compassion, we have souls and conscious - but hey forget about that - I just want some ass because I'm an animal!
I know people here hate morality but Truth is the "high ground" not darwin animal behavior. If you think that you are going to have prolonged desire for your wife forever then you are delusional! The flesh decays and the eyes lose their passion. To base everything on sex/desire is to say it is ok to get a divorce because you no longer have desire for your wife at the physical level.
So it is the exact opposite of what you state - it is the companionship, empathy and compassion, and other human qualities, that have nothing to do with desire or sex, that keeps marriages and people together!
