Ok, I have to admit that I did laugh at that, but only because the show is supposed to be comedy/satire. It's the people who say the same stuff completely seriously who scare me.
I hear you, but why not go against the flow by declaring that "old people having sex" (their words) was having the Best Week Ever instead of grouping it with the antics of Oprah (that did make me laugh) and Margaret Cho and naming them all mood killers?
But really, Selby as "old man"? As a friend mentioned, he and Harrison Ford are the same age, so the problem the media has is likely in the pairing of the former (Selby) with a woman his own age and not the latter (Ford) with women 20+ years younger. Clearly, it does not consider HF an old man, or LucasFilm would not have cast him in the final adventure of Indiana Jones.
Anyway, D Friedlander, there actually is a topic dedicated to Tell Me You Love Me on this board, and more in the archived Calendar boards.
