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?
It is very good question. I don't believe in God. But ıf I had believed in, I think it is sexless. Because it created men and women sex. It had to know both characters of men and women. It had to act like men and women.
When you read the book of Genesis, you can see that God created a man and a woman in his image.
So, both man and women represent God and both of them have God's characteristics.
If you look at the nature, you also see that everything is created in pairs, animals, plants, even atoms have 2 poles, positive and negative.
So, it's obvious that God can't be only man or only woman but both.
From this perspective, it's more correct to call God parent than only father.
