Michelangelo drew Adam with a schlong before God even breathed life into him, and who are we to argue with Michelangelo?

There’s a wonderful work of art, portraying God pointing at Adam, who is pointing at Eve, who is pointing at the snake.
God created Adam in his own image, created He him. So did God have a penis? If so, why?

What the Bible didn’t mention (and neither did the nuns at your religious school) was that God took two of Adam’s ribs. One of them, he used to create Eve.
Ask Mary. 
God created Eve to stop Adam shagging all the animals.
Does this lay to rest then the question of whether God is a man or not?
Well, Lilith was made at the same time as Adam (although I think her story qualifies more as fan-fic than divine revelation) before there was Eve.
