Saying that it is magic/miracle is probably more easy to understand than actually going into it. My will makes things happen is the simplest way I can put it.
Gods are shaped by how we're perceived, and I'm generally thought of as a very physical god given my domains. Hard to be thought of as sexy and graceful without a physical form, you get it.
I absolutely could. Like I said, I could get you pregnant or help you get pregnant if you wanted to do it your own way.
