The things my people come up with, according to Walk Taken
"Rapeex is an anti-rape female condom invented by a South African woman. The condom is inserted manually whenever she is traveling alone, late or night or thinks she will be in a situation where she might be vulnerable to being raped. When the man enters the woman, sharp microscopic barbs that are inside the condom hook on to the man’s penis. This would ideally give the woman time to escape. The condom can only be surgically removed (therefore alerting the hospital and police), but will not cause any major damage if the man get helps immediately."
