Gotcha!

Thanks for clarifying your point for me. And I apologize if you felt that your points have been dismissed, or that you have been slighted in any way – I assure you, that in almost every post I looked for solid, concrete resources and I am satisfied with what I found.
I do agree with the premise of at least one of the quotes above, “Make sure she knows this before you get married. Not many women can climax from just intercourse, and she deserves an orgasm just as much as you do” I firmly believe that both spouses be on the same page as far as what is considered acceptable in the marriage bed. That should be addressed in Pre-Cana or in pre-marital counseling.
I read what you posted. Again, JPII does not anywhere in his document state that oral sex, stimulation, foreplay (whatever name you apply) is acceptable.
Which document? ToB or LAR? Because, in LAR, JPII does. (I
did admit that it’s not in TotB, and referred you to LAR.) In the last section of LAR, titled Sexology and Ethics, he explains that a husband must take into account the different sexual arousal rate of his wife so that “climax may be reached by both the man and the woman, and as far as possible occur in both simultaneously.”
pp 270-274: Anatomically, a man must be conscious and wilful for sexual intercourse to take place, while a woman could be a passive recipient. Female arousal is a process which grows and diminishes more slowly than in a man. Since there is a moral requirement than the woman be fully involved, this requires considerable restraint and self-control on the part of the man. If a woman is not brought to orgasm and so to natural detumescence, there will be negative consequences both physiological (genital inflammation) and psychological (frigidity resulting from repeated lack of satisfaction). Feigning orgasm is counterproductive if a long-term trusting sexual relationship is to be maintained.
pp 274-276: It is clear, then, that what is needed is not so much training in technique as the fostering of a “culture of marital relations”, a culture in which mutual understanding, borne of education and a relationship of trust and good communication, comes naturally. The man must learn to offer his wife expressions of tenderness for the onset and decline of her arousal.
Yep, it’s in there. And the last sentence? That is foreplay. And afterplay.
In addition to quoting from LAR, I offered two explicit quotes from another Vicars of Christ, Pius XI, from Casti Connubii:
Marriage is a mutual commitment in which each side ceases to be autonomous, in various ways and also sexually: the sexual liberty in agreement together is great; here, so long as they are not immoderate so as to become slaves of sensuality, nothing is shameful, if the complete acts - the ones involving ejaculation of the man’s seed - that they engage in are true and real marriage acts.
#59: “For in matrimony as well as in the use of the matrimonial rights there are also secondary ends, such as mutual aid, the cultivating of mutual love, and the quieting of concupiscence which husband and wife are not forbidden to consider so long as they are subordinated to the primary end and so long as the intrinsic nature of the act is preserved.”
I even went through some of Aquinas’ Summa to explain that, with right reason, these acts are not sinful within the unitive marital embrace.
Because this particular act was at one time considered at the least, immoral or at best, illegal (see post on sodomy) I think the burden of proof falls to those who, with certainty, proclaim it acceptable. Since TOB is the primary source quoted repeatedly, I simply asked where it specifically states this sexual act is now acceptable in a Catholic marriage. Apparently, it does not.
You’re correct, which is why I discounted TotB and used at least three other resources: Casti Connubii, Love and Responsibility, and St. Thomas Aquinas. And yes, Christopher West’s book ON TotB addresses it, though it is only alluded to in TotB itself.
