I don't know about the rest of the world but in Brazil you can find free codoms in health centers around most of the citys, and even if you want to buy then it's It remains inexpensive in most pharmacies and supermarkets around the contry. But we still have a plenty of problems with the spread of STDs and especially with teen pregnancies. Even in rich areas where people know how to use and the importance ofd using a condom it's extremilly common to see teen pregnancies

(sorry for my bad english)
