GENESIS 2:25
 

[NKJV]

And they were both naked, the man and his wife, and were not ashamed.
 

[TLV]

Now both of them were naked, the man and his wife, and they were not ashamed.

Let's first share the testimony that the Lord God had finally fulfilled His Promise for the man, for God had made for the man a helper suitable for him. The Lord God be glorified for providing Woman for Man: Thank You.
 

It's no longer "The man being alone" anymore, but has become "The man and his wife." So the issue of loneliness passed but then another issue, that of nakedness, became the next in line.
 

In the Bible verse above, both the man and his wife were naked, yet were neither ashamed nor embarrassed. And I want to bring out something mankind had that angels do not have, and also something angels had that mankind did not have in the Bible verse above.
 

*1* Marriage: The man had wife; but angels do not have and must not have.
 

*2* Shame of Nakedness or Knowledge of good and evil: The man and his wife did not have either shame of nakedness or knowledge of good and evil, and must not have them; but angels have them.
 

This means "Shame of Nakedness or Knowledge of good and evil" was the forbidden thing to mankind, while "Marriage or having wives" was the forbidden thing to angels. I assume you already know the story of what happened when mankind breached the law into acquiring the knowledge of good and evil, and then acquired shame of nakedness and thereby mankind became like angels or gods in knowing good and evil. I also assume you already know the story of what happened when angels breached the law into acquiring wives of the daughters of men and bearing children or offspring through them. Or how sufferings today came by those.
 

In the top Bible verse above, the man and his wife were yet in the "Class of Animals or Lower Carnal Creatures" and not yet in the "Class of Angels or Higher Spiritual Beings." Animals are by default made to have sexual intercourse or mate, procreate and be naked without shame of nakedness. If any animal seems to be hiding its nakedness, its not hiding it for shame but hiding it to prevent access: the animal is not closing up for others not to see it, but for others not to touch or access it especially when the animal is not in the mood but the other ones are in desire for it. So animals do not have shame of nakedness even though many of them do close-up or retract (withdraw) their nakedness when not in use.
 

But the man and woman were were not using their nakedness for something productive or procreative, and yet they were not closing up or retracting (withdrawing) them: and yet they were not ashamed nor embarrassed.
 

At that stage, there were three steps for man to fully become as the angels. It should have been two steps if the man was not married and had no wife; for being married makes them 3 steps:
 

*1* Acquire Immortality or Living Forever.
 

*2* Acquire Knowledge of good and evil.
 

*3* Acquire Death to dissolve the marriage and resurrection of the dead to live forever without marriage.
