Let's consider the all-too familiar case of a young, wealthy college-educated man who likes a young, college-educated woman. On their second or third date (or, perhaps, first!), the young man decides to treat his young friend to a fancy, expensive evening. He likes her, and she likes him; however, he is, after an entertaining "night out," expecting to do some fornicating (a mortal sin which will send both of them to Hell forever, if they consent to such an act with each of their own free wills) but she is "not so sure."
Their evening goes wonderfully. After a wonderful meal, a stop at a bar, and a quiet car drive (our young man is rich, safe, and not intoxicated), they decide to return to her apartment. They talk for a hour or two, and while sitting next to each other, our young man gives his date a gentle kiss on her lips. She reciprocates, out of choice, partly because she enjoys it, partly because she wants to preserve their relationship; but the young man continues into the realm of "innocent" foreplay. She follows for a bit, but then says, "No." I leave it to the reader's imagination as to what could occur next in this all-too-common situation.
"Does 'No' mean 'Yes'"? I am sure that this is a staple of crises counselors, "shop talk" as it is called. Of course, there are but two possibilities when a woman, in such a circumstance, says "No":
1) The more probable: She means what she says, and she says what she means.
2) The less probable: She's lying, perhaps trying to play some sort of psychological game.
In either case, the woman in question knows what she wants and which of the above two "options" that she truly desires.
Modernist theologians within the Catholic Church would have us believe that the woman in question does not know what she truly desires. They would have us believe that such a woman, even if she explicitly says "No," that she, in fact, does not truly desire that outcome. They would have us believe that if she truly "understood such and such," then this is what she truly desires, therefore, her explicit desires and/or statements are not what she truly desires. They would have us believe that even though she is saying "No," if fact, she may be saying, "Yes," perhaps if she only knew what a wonderful guy she was dating and the as of yet unknown joy she would be having throughout her life if she only would have sex with him now -- the bright and marvelous future with wonderful children living in a big, beautiful home, driving a new, spacious SUV with this wonderful, loving (but somewhat "sexually repressed") man as her husband.
In the world of Catholic modernistic theology, "No," in fact, means, "Yes."
