There is apparently a device designed to be worn in the vagina as protection from rape. It has razor sharp teeth inside that latch onto the penis and can only be removed in a hospital where presumably some questions will have to be answered.
This also brings to mind the film coming out soon, Teeth, regarding a "natural" version of this device.
Talk about "ouch." I wonder if it has actually worked as intended. I also wonder if any would have been accidentally left in during consensual sex.
