At this time period Adam was just created and he felt very alone. He needed companionship, but little did he know it was going to be Eve. He had the animals, but he thought that wasn't enough for him.
God had then created Eve who would be a wife to Adam and they would live a long happy life together, until she ate the fruit and then there was original sin.
This is the time when Adam and Eve felt no shame that they were naked. They were not afraid that others may judge them because there was no one else that could judge them. They knew they were loved by God either way.
