I believe here’s what you’re missing SM. The bonding has to do with giving themselves fully and completely to one another. They don’t hold back.
Condoms or Birth control is like the husband or wife saying during the time of love making: “I don’t want to make love to the part of you that creates babies”.
I’ve heard this a million times in some variation or another, yet strangely it seems to make no sense. I wonder if it’s because it’s a fallacy of non-sequitir, which would mean it actually doesn’t make sense.
How is a condom or birth control “like” the husband saying “I don’t want to make love to part of you that creates babies” How? How?

- If anything, you are making love to that part
This is in no way any kind of reasonable explanation, it falls short on so many levels, primarily in cogency. Let me try to rephrase it into a structure of an argument:
- Condoms and birth control are wrong (premise)
- They are wrong because the husband/wife is (implicitly) saying they don’t want to make love to the part that creates babies (reasoning)
Not only does it not make sense, it doesn’t seem to even point in the right direction of explaining the Church’s position.
So he/she is not accepting their spouse 100 percent and therefore it injures what is meant to be a pure conjugal act between husband and wife. In NFP they are still accepting one another completely during love making though it happens to be at a time when she may be infertile. And let us not forget that the ‘possibility’ of conceiving is still present.
What’s happening here is you’ve read parts of Theology of the Body, or something along those lines, not fully understood it, and now are trying to explain it to someone else, and blundering everywhere.
So I’ll bite:
How is the use of a condom not fully accepting the spouse? It injures a pure “conjugal” act? How are they accepting each other fully in NFP when a lot of these couples are intentionally intimate during a period when they know that pregnancy is not going to happen? The possibility of conceiving is present with the use of a condom too, and couples know this as well. It’s more effective than NFP however.
Pope Paul VI’s encyclical letter ‘Humanae Vitae’ is an excellent read on this topic and can be found here.

"Then, this love is total, that is to say, it is a very special form of personal friendship, in which husband and wife generously share everything, without undue reservations or selfish calculations. Whoever truly loves his marriage partner loves not only for what he receives, but for the partner’s self, rejoicing that he can enrich his partner with the gift of himself."
It would have been great if you had read my earlier post in which I recommended the reading of HV to the OP, and now you’re recommending it to me too

- I have read it, and it’s not that all that conclusive, nor has it been for many Catholics either.
I can retort back at Paul VI asking him, or whoever assisting him in writing that encyclical, by posing a specific situation - What if the couple are in dire financial need, and really cannot afford having another child? Should they use NFP anyways and risk bringing a child into this world when at the moment they are in a risky financial situation, or perhaps the man is unemployed?
I find “selfish calculations” funny too, because NFP revolves around doing those interesting calculations, the period of the month, etc.
