"Love means telling the Truth, at the risk of being hated". So true. Isn't that exactly what homosexuals have been doing? They've been sticking up for love at the risk of being scorned and reviled by society.
Natural Family Planning requires couples to abstain during fertile times, which just happen to be the days when a woman's libido is highest. So saying it involves a denial of sexual urges is not that far off base.
Also, it isn't as easy as some people make it out to be. It requires careful record keeping and if a woman has an irregular cycle it can complicate things. If it's not followed to a tee, it can have a 25% failure rate. That means 2-3 woman out of 10 will become pregnant during the first year of use. And of course it does nothing to prevent against STDs.

If a woman is not in a position to have a child financially, emotionally, or it can pose a threat to her health- she shouldn't be denied access to contraceptives. Saying a couple should just remain abstinent isn't always realistic.
