I think he needs something empirical to give his wife, not anedcotal "I know this horny lady over here, and this hottypants over there, and ..." Harder to 'SPLAIN, too.
If you can't find any good articles to share with her, I'd just dismiss her with a "You know, W, you said something yesterday that really amazed me. You know, I could take the time to find you people to talk to, or even give you some of the hundreds of books, articles, and entire websites devoted to the subject, but do you REALLY believe that there are no women out there over 30 who want to have sex more than they are having it?"
Just be sorta incredulous, ya know?
Whaddayathink?
You could also give her the link to one of the OTHER BBs out there, and just not THIS one. Redbook has a "Clashing Libidos" one that's pretty good; I'm sure there are others.
