I suggested the possibility that Adam and Eve did have sex before eating the fruit. I used The Blue Lagoon as an example of the credibility of that possibility. If you haven't seen the movie and can't Google it, I'll be happy to elaborate. If there's something I haven't responded to, feel free to specify and I'll elaborate on that too.
The bulk of my last post was in response to:
Sex isn't rocket science or aviation. It is, quite obviously, something that can be done without the knowledge of good and evil and it is done without the knowledge of good and evil by every species on earth except for man.
I was essentially exploring the usefulness of this statement to make sense of the idea that Adam and Eve could be intelligent sexually mature adults without the ability to make the sort of moral choices that everyone makes today.
