Hi McKay Donald! Thanks for reading and for your thoughtful, informative response. You make a valid point. I wouldn't characterize your comment as quibble. Just sayin’.

So maybe my AP’s sex drive was strong — so much so that it felt like something that was difficult for him to live without. In any case, I do know that he wanted to be having it with his wife and wasn’t. Maybe having it with me was a way for him to have his drive met and also stay married. Food for thought! Thanks again.
