I actually read a story awhile back about how infant rape is a common occurance in some parts of Africa because of a belief that sex with a young virgin will cure AIDS. There, some men will do this to babies as young as newborns, and it is very hard to catch the perpetrator. I hope that none of these little girls retain any memory of this horror.
I will try to post the story if I can remember where I saw it (I think it was in the Lancet or the British Journal of Medicine).
