Sorry to be posting this one out of order. That said, I'm not sure it merit's inclusion because, yet again, I have to cry inconsistency. Ellen has emphasized in numerous posts, beginning with this one, that Alan was bad in bed. Since when is she extolling the health benefits of their sexeueal relationship, especially years later?
The only ret-con I can think of is that he was good sober but bad drunk, and the more often he was the latter the less Ellen could remember (or wanted to remember) the good old days. I shouldn't be doing this work, however (nor do I want to hear anything gross from Vinnie). Make it right, narratrice.
