Ladies goodnews! Scientists invent Anti-Rape Condom with teeth for women (Photos)

This specially designed anti-rape condom, Rape -aXe condoms are designed to wear like tampons. The inner portion contains teeth. Once a penis enters into it, it gets stuck and only doctors can remove it.
This will give the victim under attack the time to escape.

                                          

Dr. Sonnet Ehlers who worked with rape victims for four decades believes her product would discourage rapists

Once the spikes containing condom gets hooked on, it creates terrible pain making the person even unable to walk, incapacitating him.

My question is how will Ladies know when they would likely be assaulted..
