I think that given the controversies with Catholic schools across the world, the promotion of unprotected sex in Africa, and the general brainwashing, maybe they don't do such a good job.
Controversies?...... and the Catholic Church doesn't promote unprotected sex in Africa or anywhere else. The Catholic Church promotes sex between married couples only. No premarital sex, and abstinence, which is more reliable in preventing STD's and pregnancy than all the condoms in the world.
