[As you well know...]

First, I genuinely could not care less if you use this technique in your family or not. The ONLY reason I included it in the book is that I was aware that some families, with mature children, are already doing this. I felt it would be a service to those families to provide guidelines regarding modesty and propriety so that such a technique could be done in the most respectful way possible.

I do feel somewhat favorably toward it because--done properly and respectfully--it can demystify the sexual cycle, and the Holy Father tells us, in Love and Responsibility (c.f., the section on Sexology), that giving such information about both the goodness of the body and how the body functions is a good and useful thing

First of all, he says he doesn't care, and, then he tells us he is somewhat favorable to what he doesn't care about and then he intimates the Pope advocates the same thing...

Does the Pope really tell us it is a good idea Bubba chart Bulah's cycles?

Anyone have a citation from Love and Responsibility?

His summary comports with the thesis of Love and Responsibility.

But I am CERTAIN that JPII did not endorse using brothers/sisters for purposes of "education" in the document.
