I would say beware of taking a legalistic, mechanistic approach to this, e.g. “the church says every act should be open to life, but the couple is 100% infertile due to surgery, so there can be no conception, so then anything goes!” or even with the attitude that anything goes so long as you “finish in the right place”.
Whatever the couple does sexually should be in keeping with the dignity of the couple, which for example would preclude doing anything violent or demeaning or unnatural. Now I think the church is intentionally a little vague in setting out rules for exactly what you can and can’t do, when, where, and how depending on your age, fertility, etc. Context and intention are very important… is oral sex something that is agreed on mutually, and performed and received with love, and leads to a strengthening of the marital bond? Or is it a “forbidden pleasure” that the man has heard his buddies at work talking about, or seen in a movie, and wants his wife to do it so he can get in on the action, and infertility is just a rationalization for trying it out? Because in the latter case, it would be wrong, even if it is followed through with normal intercourse, because he’s objectifying his wife. And in the former case, I’m not sure that it’s 100% wrong if occasionally it doesn’t culminate in normal intercourse (with all due respect to “Good News About Sex and Marriage”). It’s a fine line, but I don’t think it’s the church’s intention to specify that the male ejaculation itself and the sperm contained therein are what’s sacred about the sex act, and so long as that ends up in the right place then everything’s fine. But then I think it’s wrong if you use that reasoning as a dodge, and make oral sex an occasional focus of your lovemaking. Nor should any other specific act or body part be the focus - it has to be the whole persons, and the sacramental bond that unites the couple, that is the focus.
Sorry if that makes things more confusing…
