A tampon with a needle on it should prevent rape and should give a woman back control over her body. The needle in the tampon will sting each "object" that will enter the body on that given location.
Only the thought will keep men from even attempting. The weapon, called "femDefence", is developed by the artist Lars Lindells as a graduation assignment.
God... even the *thought* of getting a needle in your peepee makes me hurt.
