I have been reading a bit of it esp Jesuslives contributions.
I think what she said about how there might have been sex before 'the fall' which didn't end in pregnancy (who knows?) is something to think about, after all, Adam and Eve were both naked and not ashamed.
They probably were just being human and naturally curious about each other for the most part and wouldn't have thought it was something to be ashamed of, or hidden away. Maybe they were in the courtship stage of getting to know each other.
