Ok so the bolded part above is the most important. “Just because it feels good, it is not right”.
You and your husband had a bond. So does the man and woman who engage in premarital or extra marital sex. Therefore now we have to see if a relationship/bond made with contraception is GOOD or BAD.
So now let us analyze if your bond or those of people who use contraception is morally valid or not.
SEX in order to be an expression of LOVE, needs to be the complete gift of each other and acceptance of each other during the act.
In the case of covering the other spouses face or using contraception, it is not complete giving. Even if the two agree to it, the rejection is still there.
Now I think you saw why it was important in the face case. If your husband decided to put a cloth over your face because he didn’t like the look of it that day, then you certainly see it as a rejection, right?
Now the fertility that is in you, and in your spouse is also something important. It is just like the face. The only difference is that majority of the population don’t VALUE it or consider it as a part of who they are. This is why you would FEEL hurt in the face case but not in the fertility case. But in an ideal world, you should care about your fertility just as much as your husband cares about his. It is partly what defines who he is and partly what defines who you are. So the problem here is actually that you do not FEEL that it is much of a problem to reject infertility i.e. its not that big of a deal.
But as you have agreed above, whether you are doing the right thing is not measured through how you FEEL . It is about whether you are doing the GOOD thing. But as seen from above, though you might not FEEL it, and though your husband might not FEEL it, you two are doing something IMMORAL towards each other. You are rejecting each others fertility.
God wants you to love completely and give yourself completely. Not partly.
God Bless
