Mormons usually will not have sex until they are married. They don’t want to screw up their chance and becoming celestial gods. Therefor, they rush into marriage, which is driven by their lust. Then, only after they’re married they realize that maybe they just wanted to f**k this person more than they wanted to spend the rest of their lives together. Or that, “Wow, this person is really an asshole, I had no idea since I never lived with them or got to know them better”.
As far as the animal kingdom goes:
Different gender species have different motives when it comes to sex. Generally speaking, the males are trying to spread as much of their seed (genes) as possible. While the females are trying to find a suitor with not only the best genes, but in many species, a male who won’t abandon the female and her offspring, as well as offer protection, food, etc.
This is the same game humans play, only on a much more complicated and masked level. We’re no different, just more confused.
