South African doctor invents female condoms with 'teeth' to fight rape (edition.cnn.com)

If it can be put in without harming the woman, presumably it can be taken out just as easily. Why wouldn't a rapist just fish it out before assaulting her?

It might work in cases of domestic abuse, but then it also might be seen as a vindictive act (getting him back for something other than forced sex).

Regardless, I hope we can survive our adolescence.

Wouldn't this just make the rapist angry, especially if he found out too late? Angry rapist could equal dead girl...

EDIT: After reading the article, I see that others think so too:

Critics say the female condom is not a long-term solution and makes women vulnerable to more violence from men trapped by the device.
