Honestly it's too much to really get into because it requires a conversation about biology, philosophy and sociology. Just to keep it short I would answer that question like this: "like most animals do."Interesting. I respect that. But I am curious how you believe we were meant to interact and procreate?
There is no place in nature where every male is expected to have a female. In fact, very few places in nature where males and females interact outside of breeding. Not to say males and females should not interact but the way we couple now is extremely forced and unsuccessful. That's why outside of religion beliefs people just don't stay together.
