I don't know if you have seen it, but there is a documentary out on DVD called " I Am A Girl ".<quoted text>
That's what they said in a book I read about third world women, called Half the Sky by Nicholas Kristof and Sheryl WuDunn. The most likely way for a woman to put herself at risk of HIV was to get married.

I think you would find it interesting.
