As for the church being a teacher of sexual morality that is probably an even more inflammatory subject than this one already is.
The new study shows that by age 20, 75% of Americans have had premarital sex. That number rises to 95% by age 44."

It's just that the doctrine isn't working, and it never has. Teaching people about condoms doesn't increase non-monogamous sex ratio's (those are high already), but it does increase condom usage. The guilt and exceptionally "sex-negative" culture that's been fostered in Western Culture, a large part due to Christianity, has caused us tremendous problems through sheer ignorance of human sexuality.
Unfortunately, it's often the women who are at the most at risk, even those in monogamous relationships (women are at a much higher risk of AIDS infection) as it's statistically the male who cheats and in many societies the ability to divorce is limited. This doesn't even touch on the power birth control and condom usage has given women in fully monogamous relationships to properly and effectively plan their pregnancies.
Oh, and should this even be hackernews?
I do not think the Catholic Church is unaware of this information nor does it dispute its veracity. I don't think you really believe that the Catholic Church is "sex negative," either. They strongly favor the association of sex with procreation, which is different than being against sex altogether. It is a minority viewpoint, but aren't minority viewpoints valuable and worth examining to see if society has gone too far in the opposite direction?
I also find it odd you see Western Culture as "sex negative." I would be surprised if you could name more than a couple popular Western TV shows or movies that endorse anything like the Catholic viewpoint on sex. Or did you mean something else by "sex negative?"
Here is a really poor wiki definition of "sex negative" (http://en.wikipedia.org/wiki/Sex-negativity).
"Sex negativity" is more about a lack of tolerance of different forms and viewpoints of sexuality.
I don't think that upon reading the Catechism or looking at a history of the Catholic Church and it's view on sex/sexuality you come away with a very comfortable view of the actual sex act. Part of this may be due to the fact that those that wrote the doctrine were suppose to be chaste. It's interesting reading how the Catholic Church changed it's early viewpoint from allowing priests to marry early on, to outlawing it (in all but a few loopholes, such as getting the "calling" after you are married).
Most of the doctrine seems to view sex as some unfortunate necessity for procreation, not something to be celebrated by itself. It's never been that comfortable with sex for pleasure. This is in stark contrast to let's say the Greek/Roman societies before the rise of Christianity.
However, I feel like the word itself is partly biased because it assumes that a "sex-negative" viewpoint is bad and a "sex-positive" viewpoint is good (similar to the atheists movement to call atheism "brights"... which makes it seem like everyone else is dims) instead of using more neutral definitions.
This is stunningly nonresponsive to the issue and is, regrettably, par for the course in these discussions.
We're Catholics. We like medicine. Flu shots are wonderful things! We like killing people a lot less. In vitro fertilization requires the creation and destruction of many, many embryos. Well over seven per attempt, when everything goes right, although the denominator is not really relevant to our reasons for disliking it.
The debate on whether an embryo is a person or not (in the moral personhood sense) is not an open-and-shut question of "science", and if a little humility about the limitations of knowledge is appropriate, it is probably also appropriate for those whose advocacies necessitate the destruction of life.
If flu shots required stabbing an African in the belly to produce, Catholic moral doctrine concentrates more on the immorality of stabbing the African in the belly and less on the exact flu-shots-per-African ratio (or Africans-per-flu-shots ratio).
One of the greatest tragedies of our time is happening right now in Africa, and if it was up to the Catholic church it would be a lot bigger than it is already
Nobody has ever died due to an overly strict adherence to Catholic teaching about sexual morality. Really, think about it.
Then go the next step: if blaming the Catholic church for deaths in Africa for opposing condoms is logically sane, then it must also be the case that condoning sex outside of marriage kills Africans. Which, I rush to mention, is inane.
