(My conclusion:Apparently for Adam the Father of Mankind, that apple in the Garden of Eden was not the first tempting forbidden fruit)

"..Perhaps the first passage that speaks out against bestiality (albeit, indirectly) is found in Genesis. Consider for a moment the creation account with Adam and Eve:

And Adam gave names to all cattle, and to the fowl of the air, and to every beast of the field; but for Adam there was not found an help meet for him. And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man. And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man” (Genesis 2:20-23, emphasis mine).

Adam rightly recognized that no animal in the world was a proper match for him. He could have no true love, no true fellowship, and no true intimacy with a mere beast. Therefore, God made Adam an help meet. Adam was so excited to see a woman that he exclaimed, “This bone of his bones and flesh of his flesh.” I’ll guarantee you that Adam was the happiest man on the planet when he first laid eyes on Eve (he had to be, he was the only man on the planet!).
