Fie upon it I say. All of this is based on the premise that creating life through sex is somehow... special, or powerful. Now, perhaps I'm talking out my ass, never having had a child, but I look at it this way: Any pair of idiots can result in a kid being squeezed out.
The powerful act of creation is not spitting the kid out. The powerful act of creation is not in the making of a new life- but in the care of the new life. In the mental and physical excersises of shelter, care, guidance and growth.
Creation isn't making a new life, it's make a new worthwhile life.
