I know, right? I remember when I had just joined the LDS, and was with my professor and his family and the subject came up. I balked when I hear that God had sex with Mary and they explained to me that “God has a physical body, he cannot do things outside that physical body because he has to obey the laws of the universe, so he came down and created Jesus just like your parents created you, through sex”.
At the time, it made sense.
Please find a link where Mormon leaders state that God the Father has literal and physical sex ( intercourse) with Mary or that Mary was not a virgin when Jesus was born.
Since it is soooooo believed by you it should be simple for you to find a quote in a nanosecond or two.
I see a lot of implied imaginings from the minds of people I consider to be pathologically obsessed with Mormonism.
