Many people are very serious in their selfish and worldly desires and unafraid to share way too much. Many women won’t and some can’t take hormonal contraceptives and latex allergies are not that unusual. Others just don’t like the available ABC methods for whatever reason. I am not sure what makes posters on CAF so sure that everyone has trouble abstaining for reasons that aren’t serious or grave or life threatening. To many people, lifestyle threatening holds more weight than anything medical. They avoid, avoid, avoid and then they get medical help to have a baby. Often the try for a baby once their health is in decline rather than fear for their health. It’s all about being in control of every aspect of our worldly life, and for several couples that is the draw towards NFP. It puts them in control of all aspects, including their urges. Of course that isn’t the case for everyone and I agree many Catholic couples would not ever dream of that. Continuously stating it is next to impossible for anyone to misuse NFP, though, is simply untrue. And illogical.
