Funny, he posted about how sex should only be for procreation...how does sexting, sending pics of body parts fit into that deeply-held belief...
Maybe the procreation thing is his wife's belief? She had to have known his screen name... He used the same handle on almost everything. So, maybe it's possible that he posted that for her benefit? I wonder is she was on Reddit? And I wonder if that could explain his straying and her saying they had intimacy problems?
