Your comment reminds me of a married woman I know who, after years of taking the pill, confessed that she always felt like a prostitute... she felt used. Mind you, she and her husband were never unfaithful to one another, yet she felt the consequences of the "unnatural" aspect of the whole thing, and probably was bothered by her conscience as well.
The ironic thing in our society is that no one seems to recognize the obvious: if you take children out of the marriage equation then the relationship, instead of being based on self-giving and fruitfulness, becomes inherently centered on self indulgence - not exactly the best centerpiece for a marriage to last!
In my opinion the whole contraceptive mentality is to blame for all of the sexual problems of the day (and other problems as well). Simply put, if it is not about having children within marriage, then it must be about pleasure; and one can seek that pleasure when and where they prefer, that is, if it is not about having children with marriage. The results of contraception in society, although there is a lot of cover up and denial on this, are: depression, divorce, cohabitation, adultery, homosexuality, abortion, etc.
I think it's time to wake up and smell the coffee on this point, even if this means owning up to having fallen short of the mark in the past.
I have had the personal experience of this, in the years that I taught Fertility Awareness.
One woman told me, with her husband sitting next to her, that every time she took the Pill, she “hated” him. She had tears falling from her cheeks. It was her first chance to let him know the truth. (BTW, things worked out very well for them because she was faithful to the truth. They were Baptists, and they went on to teach other couples what they learned in the FA class.)
That woman was, I have no doubt, one of many (who probably never had her courage to tell their husbands the truth).
