Sexuality is at the heart of who and what we are as humans. Anything we do or don’t do that leads to a selfishness, or a disordering, or a halfheartedness, in our sexuality, lessens us as a person. Sexual intercourse is meant for a married couple with the purpose of, to put it simply, bonding and babies. If either of those purposes is deliberately blocked, the sexual union of a couple is less than what it could be. Many people would say that choosing to practice NFP is both the hardest thing they’ve ever done and the best thing they’ve ever done. The level of communication required to practice NFP effectively is a great benefit for a couple, as are the times of abstinence needed. Marriage, and sex in marriage, is not about “getting it whenever you want it” as many, regrettably (but in a way understandably) seem to believe.
The fact is, that NFP is possible, and on the face of it, has tangible benefits. I think we buy into the modern crisis of imagination, or poverty of imagination, when we suggest that it’s impossible or not worth pursuing.
