You know the old stereotype about adolescent boys who learn the facts of life from other adolescent boys when they have no one else they feel comfortable consulting. I suppose, in the Internet age, that that's gone the way of the dinosaur. For better or worse, information is only a mouse click away.
However, I that old stereotype occurred to me as I was skimming some comments at Called to Confusion:http://www.calledtocommunion.com/2010/07/contraception/Start with comment #149, and take it from there.
Here we see a commenter (David Meyer) who's asking if it's morally permissible for a husband to have conjugal relations with his pregnant wife.
Of course, that takes the Catholic position to its logically absurd conclusion. But for now I wish to focus on a different point:
Why doesn't it occur to David that maybe, just maybe, that's a question he should ask his priest? And why does it not occur to the other respondents like Sean Patrick to tell him that he ought to consult his priest? Isn't the priesthood the retail end of the Magisterium?
They attack sola scriptura. They attack the right of private judgment. They insist on the absolute necessity of the Magisterium.

Yet here they are, groping for answers to questions as practical and fundamental as conjugal relations. And where do they go for answers? They turn to each other, like adolescent boys who, instead of consulting their parents or family doctor, use the locker room as their information clearinghouse for SexEd 101.

This is from the guys over at Triablogue. :D
