The confession of both the man and the woman when confronted by God was "I did eat" not "I did touch". So, if "touching" (having sex) is different than "eating" (???), then the confessions of both were not of the sexual nature; what precisely did they confess to doing? What precisely is "eating"? They apparantly were allowed to "eat" from every tree save one; I don't believe God told them to have sex with any and all trees. Therefore, what was the actual act which was permitted with every tree except the Tree of Knowledge of Good and Evil.

I did "EAT" was the confessed sin.
