It is not plain at all in Gen 1;28.
They were told to reproduce and could not without desire.
Your last shows that they knew nothing of reproduction and sex as they had no knowledge of nakedness.
Did you know anything of reproduction before you knew what nakedness was?
Of course not. No one does.
It is called innocence.

Animals do it all the time and is programmed into the female to take cane of the new born, is it not nice ? Stop bitching about your Creator and give thanks that He give you Intelligence to explore the Scripture .
You can't helped you are part of Him is just that you are bitter about something so you are trying to degrade Him.
