Which sex is God?
Does He have a penis or a vagina?
If He has either...and there is only one God...why would he need reproductive organs?
Neither, He can be in any form He want to be because He is God. Human have reproductive organs because we need it, He clearly doesn't because of His unimaginable power. But I really believe that God is in the form of energy and the MWBR are traces of His power.
