I think St. Paul was talking about couples who go for months or even years of abstinence. And this does happen because there are people out there, with good intentions to follow the Catholic Church, don't know about NFP and think you can only have sex when you want to make a baby. I've heard of a couple that this happened to. The husband ended up having an affair and the kids had to step in and explain things to their parents so they could save their marriage.
The KIDS had to explain that to their parents? And I thought my family had some awkward conversations....
Basically, abstinence never justifies infidelity. When you marry someone it is in sickness and in health, richer or poorer, good times and bad, etc. etc. That means if on your honeymoon you get in a car wreck and your spouse is horribly disabled you are still just as bound to fidelity as if your spouse was perfectly healthy.
I think our society literally teaches people that something will shrivel up and fall off if they do not have enough sex. (It won't!) Sex is great, but it should be the icing on the cake in a relationship, not the main course. You should build your relationship up to the point where you COULD go without sex for a long time without becoming unfaithful.
I work with oncology clinical trials and there are certainly times during chemo when getting pregnant is about the worst thing that you could do to thwart your treatment plan. While some new data shows that it is actually relatively safe for women in the 2nd and 3rd trimester to receive chemo without harming the baby, it is still not a good situation to be in. My husband and I discussed this one time (we have some strange dinner discussions) and he said he couldn't imagine even thinking about having sex if I was going through something like cancer treatments. He felt like there are much more important things going on that would distract him from even thinking about it. Plus, abstaining would be a way he could ensure the best possible treatment outcome.
